How did the old 1776 Constitution set up repersentation in the legislature?

The Articles of Confederation, ratified in 1781, established a unicameral legislature where each of the 13 states had one vote, regardless of its population or size. This meant that representation was equal among the states, leading to concerns from larger states about their influence in the legislative process. The lack of a stronger central authority and the inability to levy taxes or regulate commerce were significant weaknesses of this system. Ultimately, this structure contributed to calls for a new constitution, leading to the Constitutional Convention in 1787.
