The historical basis for a mechanic like this would be like the cities of Buda and Pest becoming Budapest, or Washington-Baltimore or Tokyo/Yokohama etc.
The gameplay basis is to reduce the amount of clicks needed to make decisions as the game goes on. I'd rather tell one city to make a tank than tell three cities to make tanks. It is also easier to keep track of what one city is doing than three.
The tactical basis would be that, we click three times to have three cities make one tank each (three total). Each city has say 25 production each and the tank costs 200 production. With three cities that is three tanks coming out after 8 turns. With one city that has 25+25+25=75 production, that is a tank on turns 3, 5 and 8.
Anyway as a proof of concept of how it might work
1) Start the game, cities can be founded two tiles away from existing cities
2) Discover tech or advance to new era, cities now have to be founded three tiles away from existing cities, cities two tiles from each other are merged
3) Discover tech or advance to new era, cities now have to be founded four tiles away from existing cities, cities three tiles from each other are merged
4) etc
Or
1) Unlock railroads, any two cities connected by railroads may be merged into one
