What compromises were reached at the Constitutional Convention?
The two biggest compromises were the 3/5 representation for slaves and the two house legislatures.
The Bi Chambered Legislature was a critical compromise.
The large states wanted a legislature based solely on population.
The large states were afraid that the small states would get more than their fair share of power and benefits if the legislature was not based on population.
The small states wanted a legislature based solely on the number of states similar to the legislature in the Articles of Confederation, which hadn't worked. The small states feared that their interested would be submerged in a legislature based on population.
The compromise was found in the government structure of the Iroquois federation. The democratic structure of the Iroquois faced a similar problem. There were two large tribes the and three smaller tribes. The answer was a council based on two chiefs from each tribes and a second council based on population one representative from each long house. This brought peace within the Iroquois tribes.
The Compromise was proposed by a representative that had worked as a missionary to the Iroquois. This compromise was accepted by both the large and small states. This brought peace within the colonies.
The three fifth compromise brought a temporary peace between the southern and northern states. The Southern slaves states wanted the slaves to count 100% toward representation in the House of Representatives. The Northern States wanted slavery to be progressively outlawed and the slaves counted as zero percent toward the House of Representatives. The 3/5ths compromise worked to bring agreement between the slave and free states.
These two compromises were the most critical in reaching agreement on the Constitution.
