Were the ancestors of America British?

Not exactly. Only some Americans are descendants of the original British colonists.

At that time, the Dutch were the first people to establish a colony in the United States. Later, the British seized Dutch territory and established thirteen colonies, and the British began to immigrate in large numbers. Because Ireland belonged to Britain at that time and Ireland and Scotland were relatively poor, a large number of Irish and Scots immigrated to the New World at that time. In fact, there are not many real British immigrants.

At that time, the French also established a super-large colony in the interior of the United States-Louisiana, which is almost one-third of the current American territory and larger than the British colony. In the Napoleonic era, the French sold Louisiana to the Americans to raise funds for the war, but many French people stayed in the United States.

After the founding of the United States, European immigrants were encouraged to meet the labor demand. At that time, the main force of European immigrants was Germans, so a large number of Germans moved to the United States. Then there was a war between the United States and Mexico, and Mexico ceded almost half its territory to the Americans, so a large number of Mexicans of Spanish descent stayed in the United States.
