From 1841-1850, 1.3 million people moved overseas, the greatest part around 70% went to the USA, the rest of them shipped to Australia and only 2% to Canada. A lot of people died because of different diseases during the trip and the conditions were terrible. In the USA, quarantine centers were established for arriving ships, where sick emigrants recovered. The emigration continued until the First World War. Canada and Australia reacted in a different way, because the amount of emigrants was much lower, the greatest part of emigrants decided to move to the USA. Emigrants had the poorest jobs and bad conditions for life in the USA.
The Virginia Plan was for the larger states and the New Jersey plan was for the smaller states. It was over representation in the Legislative Branch (Congress). The larger states wanted representation based on population because they had slaves. The smaller states wanted equal representation because their population was smaller without the slaves. Congress ended up with 2 houses the Senate with equal representation of 2 per state and the House of Representation based on population. This was called the Great Compromise.
