Why was the Great Compromise incorporated into the Constitution?

The Great Compromise was agreed to and put into the Constitution because the Constitution would not have even gotten out of the Convention unless the large and small states were satisfied that their interests would not be dominated by the others. Representation in Congress was originally to be based on population. The larger states would have more votes than smaller states. A plan was offered where each state would be represented by an equal number of representatives. The larger states would not accept this because they felt that smaller states with an equal vote could dominate larger states. The Great Compromise creating two houses of Congress, one based on population, the other with equal votes was agreed upon as a reasonable way to protect the interests of both sides. Compromises like this were common. It is the same as when the southern states insisted that the issue of slavery be taken out of the Declaration of Independence. If it had not been taken out, the southern states would never had agreed to it and it never would have been issued.
