Did small states worried that the large states would have too much power in new government?

Yes, small states were concerned that large states would dominate the new government, particularly during the Constitutional Convention of 1787. They feared that representation based solely on population would give larger states disproportionate influence in legislative decisions. This led to the creation of the Great Compromise, establishing a bicameral legislature with both proportional representation in the House and equal representation for each state in the Senate, addressing the concerns of smaller states.
