The British and the French fought against each other for control of India.
Probably yes considering North America was claimed as part of the British Empire. Mexico controlled it in the early 18th century so I may be wrong!

The American rebels won against the most powerful empire of the 18th century because they concored at Yorktown.
British and European were the 2 main immigrant groups. This was back in the 18th century.
Ottoman Empire of course.
There were Sufis in the Safavid Empire, but they were often persecuted and marginalized.
Canada never really "joined" the British Empire. Rather the reverse, the British Empire acquired Canada in pieces, with no volition on the part of Canadians, either the original native inhabitants, or the contingent of New France settlers in the 18th century, whom the British conquered and occupied. Just as the United States was once a part of the British Empire, which was not a conscious act. The difference being that the United States separated from the Empire, in a revolution, whereas Canada more or less evolved as a distinct and sovereign country. And even the Empire evolved, world wide, into the Commonwealth of Nations, sharing the monarch, but really nothing else.
