OOC: I decided to make a separate post for non-European affairs, i.e. colonization, Far East, etc, and a separate one for Europe itself.
IC:
1649-1700. The Colonies, the sea and the Far East.
Dissent, as said, was growing in Europe. But more on the precise dissent later - it is now more important that we note that, the way it was, many people were unhappy in Europe - out of social problems, disease, overpopulation, political grievances, many other reasons. That was why during the late 17th century especially, many Europeans moved out. It was easier, to some extent, for the Russians, who had vast eastern lands to colonize. In Central Europe, locked in as it was, things were the hardest, albeit during the Thirty Years War many Germans fled for other European colonies in America. The five prime colonial powers in the Americas were England, France, Holland, Spain and Portugal - those were the ones who emerged victorious in the early colonial wars. But needless to say, the Spanish were now the weakest, which had certain reprecussions.
But for now, we will have to examine a certain important naval and colonial struggle. Spurred by commercial interests and by geography, Netherlands and England were increasingly hostile. Trade and colonies were the primary matters. Charles I, until his death in 1657, did not want to risk a war - his situation at home was too precarious to risk it. Charles II, however, was young and restless, and felt that he could decrease dissent by a strong foreign policy. Thus the antagonization of Holland, which resulted in the Second Act of Navigation, which unlike the 14th century one was earnest. It greatly limited foreign trade, in hopes to strengthen England's own commerce, and to provoke the Dutch into agression. First Anglo-Dutch War, an ill-planned, ill-executed war, was a great debacle; the English only won the very first battle, at Texel. All other battles were grand victories of Maarten Tromp, and France, which generally was pro-English, nonetheless refused to intervenne. The defeat persuaded Charles to make reforms and to prepare for another war; he managed to skillfully use the growing tensions between France and Sweden to ally with France against the Swedish allies in Holland in 1666. The Second Anglo-Dutch War was rather better known as the Eight Years War, the first big European war since the Thirty Years one, but for now we should study the naval and colonial sides of the war. Tromp was already dead by then, but he had a worthy successor - Michiel Ruyter. Against him fought a worthy man, however - Admiral Gerard (OOC: ATL person who might have existed in OTL for all I know and care. All English admirals of the time I found so far were Parliamentaries in the ECW, and that makes them... unacceptable for such an important role). Two admirals could hardly gain an upper hand - their initial battles were all indecisive apart from Ruyter's minor defeat at Penzance. The decisive battle came in 1668 - at Cape Finisterre, where Ruyter moved to intercept the English forces sent to reinforce the militias in North America. Gerard commanded the escort fleet. In the tight battle, Ruyter won largely due to luck - the weather was rotten, and albeit this caused him much hardship it also damaged the French fleet sent to help the English and delayed its arrival. The superior disciplinne of the Dutch sailors was also important, but either way, Gerard died in battle, the English transports were mostly destroyed and the English fleet scattered. The French arrived too late to save anything, and - here, Ruyter's skill and the disciplinne of his men became especially important, for the French resolve broke due to seeming "unshakability" of the Dutch - too were defeated. The Swedish fleet then joined the Dutch one back in Holland and in 1671 defeated an Anglo-French attempt of a maritime invasion of Netherlands at Waddenzee.
In North America, New Holland was a rather insignificant colony until it begun to receive much immigration in 1640s - especially Huguenot and English (mostly radical Parliamentarist - many Parliamentarists fled to Scotland, but some chose Holland instead, or rather its colonies). This brought more attention to it, and it extended along the Hudson River towards Fort Oranje, an important fur trade outpost. Furthermore, in 1665, the Dutch, after a series of colonial border conflicts with the English to the north, have sent a small amount of troops - those troops would prove crucial while Ruyter first delayed and later destroyed the English reinforcements. The early English attacks on Fort Oranje and New Amsterdam were repulsed, and in 1673 Newport was captured. It was returned by the Treaty of Westphalia the next year, but the same treaty confirmed River Connecticut as the border between New Holland and New England; needless to say most of those colonies were, in the 17th century at least, under native control. Further south, the Dutch and the Spanish, well, mostly the Dutch ofcourse, succesfully defended the Dutch and Spanish possessions from Anglo-French forces, and captured several important possessions, including Barbados - all those were "ransomed" back at Westphalia. And further south was one of the greatest Dutch colonies - Dutch, or North, Brazil with the capital in Mauritsstad (OTL Recife). Often threatened by Portuguese rebellions, it was somehow pacified by the capable administration of Johan Maurits, but as in 1666 Portugal stood on the English side, a new wave of uprisings begun. Some sort of control was maintained in the crucial cities, whilst maritime landings secured English Essequibo and French Cayenne in Guinea. These territories remained Dutch after the war, and Maurits managed, after the rebellion was put down in 1673, to persuade the stadholder in the need of better government "if we are to retain this rich land" - basically, what was meant that the Calvinist ministers are restrained in their vigour and that the rights of the Portuguese plantation owners are guaranteed. Revolt risk was not eliminated, but after some reforms took place, combined with increasing Huguenot immigration, well, things got better. Meanwhile, in a land far, far away, this war was also fought. That land was called "India". The Dutch fleet there scored several victories over the Portuguese one and its English allies, and captured several of their trade posts, but the only significant territorial change at Westphalia was the annexation of East Timor and Portuguese holdings in Ceylon by Netherlands; most other gains were abandoned, albeit Dutch primacy in Indonesia was acknowledged.
Another European war - the First Rhenish War - also involved some fighting in the colonies, but no changes came apart from the confirmed independance of Virginia - in the years preceding the war, in 1681 to be exact, a rebellion begun in Virginia over policy towards Amerinds; the governor, William Berkley, wanted greater trade and good relations with the natives, namely Powhatans. A charismatic local colonist, one of the Parliamentarian supporters who nonetheless like those French Huguenots who moved to Quebec decided to settle in Virginia, by the name of Thomas Braydon, wanted further expansion instead, to win lands for Virginia's growing population. He assembled a reasonably-large force of volunteers, and when Berkley declared this to be rebellion, Braydon... rebelled. (OOC: in OTL, a rather similar incident took place earlier, the rebellion actually succeeded but fell apart just after that, because its leader was promptly assassinated by the penguins. Here, we have a different leader, a different time and the penguins distracted elsewhere.) In a ferocious bloodbath that followed, drunken (according to some accounts) colonists overran Berkley's mostly-unenthusiastic followers and then also beat up some Amerinds. After sobering up, proverbially and perhaps literally, the colonists realized that they just killed their governor and defeated the local garrisons. Braydon, as already said a Parliamentarian, nonetheless knew quite well that the English wouldn't stand for this, and also knew that they won't really ask questions at all. Some of the more Royalist colonists refused, but Braydon's fellow Parliamentarians grouped up with local opportunists and those who wanted greater self-government - a fairly large percentage of the colonists was persuaded by Braydon's rhetoric. The Virginian Republic was declared independant, and Braydon begun to prepare for a battle, hoping that the English underestimate him and that the Dutch, to whom he sent his son and some others for negotiations, agree to help. The first English attempt to reclaim the colony was defeated in a close-ran battle at Jamestown, mostly because Virginians knew the land much better and because Braydon turned out to be a pretty decent commander, not to mention charismatic. But the second expedition would have probably beaten Virginia into submission, especially as the Indians Struck Back, and only barely were defeated. Luckily, the Dutch, in the face of first the kapiten-generaal Ruseveldt of New Holland and then staholder William III proved only too happy to cause some troubles for the English, albeit they were concerned with the possible bad precedent, and as it was increasingly obvious that a new war would come very soon they agreed to lend assistance to Virginia, first in the form of funds and arms. And then the war came, the Dutch fleet fared not as well as previously but nonetheless, Virginia survived its early years and the English grudgingly agreed to abandon the colony.
But even before that, the English gave priority to New England, developing this colony greatly. But as it became increasingly boxed-in, strife begun to rise with France... To avoid this, the English king Charles III decided to create a colony in the Carolinas, hoping to distract some of the immigration from New England. Said colony (in OTL South Carolina), set up in 1678, was lost to the Dutch during the Rhenish War, but later returned. By 1700, that colony greatly expanded north and south, but this caused even more problems with Virginia, which also was very much expansionist.
The French were, however, the greatest colonial power of the time. Their vast colonial empire was rather underpopulated, but nonetheless prospering - New France, Pays d'en Haut, Radissonia (OTL Prince Rupert's Land - here, the English colonialism is weaker, not to mention that Prince Rupert himself continued to be a military commander, whilst Pierre Esprit Radisson, the mastermind behind the creation of the colony, for butterfly reasons, was not antagonized by French colonial authorities and instead created the French Hudson Bay Company), Louisiana, countless Carribean islands and Indian trade posts including the jewel in the French crown - Madras. But what was alarming was the small amount of immigration - mostly some Catholic Belgians and the rare Irishman, with a small percentage of Frenchmen - due to which the majority of the population was local-born and thus had a lower sense of loyalty...
Portuguese empire was definitely in decline, as was the Spanish one, albeit Spaniards did not lose much more territory during this time, even expanded against the natives. However, close to the end of the century, a very irritating incident happens some silly Scottish colonists built, well, a colony in Darien (different from OTL - the "culprit" ITTL is the Scottish West Indies Company, directed by David Bruce). There were many hardships, yadda yadda yadda, but eventually with a bit of Dutch help (Holland being a Scottish ally) the colony begun to prosper somehwat due to trade, and beat back a Spanish expedition sent to claim it. Eventually, the Treaty of Panama settled the conflict - Darien and a nearby area east of Maje Mountains and north of Sapo Mountains was purchased by the Scottish Republic, but Spain got trade priveleges and right of passage. This was exemplary of the weakness of Spanish government at the time...
Russian expansion during this era has reached the Pacific Ocean and fur trade, combined with the Troubles in Russia Proper, drew many settlers, as numerous cities were built. A limited border war with China was fought for over a decade, during which the Russians won a victory, using the unpreparedness of Qing Chinese forces for a war in the region combined with the good use of Cossacks; more experienced Russian forces secured Amur and Ussuri regions, and defeated the outdated Qing armies. However, Manchuria was succesfully defended, and albeit the Treaty of Ninguta did acknowledge the Russian gains, the Qing dreamed of revenge - if only because this defeat was immediately followed up by rebellions - it seemed to their enemies as if the Qing already lost the Heavenly Mandate. Emperor Kangxi put the rebellions down, however, and used the defeat to persuade the conservatives in the need for reform. Closer contact was established with the foreigners, especially the Dutch, numerous military reforms were undertaken... Kangxi's China quickly caught up and prepared for the next war. In the meantime, its newly-reformed, modernized army armed with new weapons, with some foreign military advisors - never prominent but still useful - begun testing its strenght in wars with the western Turkic tribes, extending the Qing realm west against the Dzungars, gaining Tibet and Qinghai.
The Mauryan Empire increasingly threatened to fall apart under the strain of rebellions, but not much change from OTL yet...
In Southeast Asia, not much changed from OTL - apart from in Siam and Myanmar. During the three "Anglo-Dutch Wars", England and France did their best to win over Siam to their side, and King Narai for his part, in spite of some hostility at the court, did HIS best to improve relations with France, encouraging modernization of Siam (OOC: as the French are much more concerned with counter-balancing Dutch power here then with extending their own, they don't act as arrogantly as in OTL and thus do not provoke the rise of a large anti-Westerner movement in Siam). Albeit the Dutch remain influential in Siam, the Siamese increasingly begin to trade with France and England - but this, as of yet, is not enough to break the Dutch economic strenght in the region. Militarily, the Siamese fare very well against their traditional enemies, routing and eventually conquering Myanmar.
