The Great Law of Peace and the US Constitution both determined that laws should be made by representatives elected by the people.
In the case of the Great Law of Peace, it was a constitution of the Haudenosaunee (also known as the Iroquois Confederacy) that was established before European contact. The Great Law of Peace established a system of governance that was based on a representative democracy, where leaders were selected by clan mothers and served the people. This system of governance was highly influential in the development of democratic institutions in North America.
In the case of the US Constitution, it established a federal system of government that was also based on representative democracy. The Constitution created three branches of government – the executive, legislative, and judicial – with a system of checks and balances to ensure that power was not concentrated in any one branch. The Constitution also established the principle of federalism, where power is shared between the federal government and the states.
So both the Great Law of Peace and the US Constitution recognized the importance of representative democracy in making laws and governing society.
