Answer:
between 1662 and 1807 British and British colonial ships purchased an estimated 3,415,500 Africans. Of this number, around 2,964,800 survived the 'middle passage' and were sold into slavery in the Americas.
The transatlantic slave trade was the largest forced migration in human history and completely changed Africa, the Americas and Europe.
Until the 1730s, London dominated the British trade in enslaved people. It continued to send ships to West Africa until the end of the trade in 1807.
Between 1699 and 1807, British and British colonial ports mounted 12,103 slaving voyages - with 3,351 setting out from London.
Three new reforms were introduced by progressives to force state legislators to respond to voter's concerns. allowed a group of citizens to introduce legislation and required the legislature to vote on it.
It established the principle that everyone is subject to the law. Even the king. It also guaranteed the rights of individuals, and the right to a fair trial.
Nativism - This is the belief that people who were born in a place should be favored instead of immigrants. For example, this used to be popular in the early 1900s, as many people thought that immigrants would take their jobs. During this time, many Chinese people were immigrating to the United States for work, but when work started to run dry, many Americans did not want them to immigrate there anymore. This then caused the Chinese Exclusion Act, which banned immigration from China.
Assimilation - This is where people of other cultures try to take in the values and culture of the majority in a society. For example, this was very prominent with African Americans and Native Americans in history. White Americans would try to assimilate African Americans, so they could be "better functioning" in society. This also happened with Native Americans, even forcing children out of their homes and taking them to boarding schools. They would then strip them of their culture by forcing them to dress differently and wear certain clothes, all to try to get them to work in society better.
Cultural Preservation - This is where culture is preserved. Culture is and has always been a very important thing to people and preserving it is important as well. This makes it so the culture can be passed on for generations to come and it will never be lost. It can be preserved by sharing your culture with others, creating things that represent your culture, preserving sacred lands that have to do with your culture, or many other ways.

Nativism, assimilation, and cultural preservation are connected by immigration and culture. While they are all very different in a lot of ways, as I explained above, they are brought together by culture.
