With it's case with the Canaries and such finally ended, the Marian Empire would like to press claims to the following:
Equatorial Guinea, Gabon, St. Helena, Tristan de Cunha, Ascension Islands, Sao Tome and Principe, Trinidad & Tobago, Grenada, St. Vincent & the Grenadines
While it seems quite large in terms of numbers, it is actually a very small addition relative to say, the Philippines, Iran, etc. as shown by:
Where Marian claims are in black.
The Marian Empire's rationale is primarily trade-oriented, but more specifically:
1. The Marian Empire gave up half of what it could have taken previously, even if it did gain an ally in the process.
2. The Marian Empire's British components yearn to reclaim several of the Caribbean Islands, in fact, countless numbers of them, but the Emperor has cut this number down to 4 for the time being. These islands will also secure a route to the now-neutral Panama C anal.
3. Besides historical claims on them, the Marian Empire would like Ascension, Tristan de Cunha, and St. Helena to assure safe routes to the Indian Ocean.
4. Cape Verde would be an excellent station into the South Atlantic. The Marian Empire is willing to compromise on these islands, however, provided it can obtain a secure enough piece to aid it's shipping southward.
5. Gabon, Equatorial Guinea, and Sao Tome and Principe are in the middle of a potentially-unstable region. The Marian Empire wishes to establish a sizeable "home away from home" here, so as to help protect the South Atlantic islands, as well as be able to ensure the political - and therefore economic and commercial - stability of Africa, and this region would be perfect, as well as pleasing the French faction of the Marian Empire. The Marian Empire is willing to shrink it's exact claim here somewhat, but would like a sizeable chunk of land in order to be able to protect it's South Atlantic possessions more easily.
