So, how do I get an alliance?

[VoiD]

Playing as GB, I broke my aliances with most people I start with so I wouldn't get dragged into any european wars and could focus on the americas, which seems to be working, the problem is that I can't get allies, sure everyone went unfriendly or hostile but now I have the Maratha and Ottomans as "Friendly" and I just can't seem to be able to get an alliance with them, I tried offering 5k, 7 techs and an american region and they still won't accept it, any tips?

They may be friendly, but that doesn't mean they want to make an alliance. Your's breaking every alliances you had already puts them on edge, but is it in favor for them at all? Do you have any enemies that's their friends? Are you a friend of their enemy? Etc...

Basically, they can love you; but if an alliance isn't in their favor, nope.

It looks like I was in their priority list or something, next turn the maratha declared war on me with a fleet ready to attack the americas in the same turn =/

if you have many enemies and few friends, other nations may take advantage of it & declare war to acquire territory.
it is best to make alliances with nations with common religions and different goals, (a few examples; great britain with prussia & united provines, even sweden, or france with spain & austria), like so, they will not see you as a threat for expanding too much or wish to acquire land that is a part of their objective too much (unless it was 1 of their starting territories).
it is also not possible to ally yourself with enemies of another ally, & you will be forced to either go to war with an ally or lose both if another declares war on said ally, keep in mind breaking promises is viewed badly by all nations & can hinder diplomatic objectives in the future.
