History and Context
The framers, having just thrown off the yoke of a king, were deeply suspicious of executive power. Their first instinct was to place the heart of the new government in the legislature—the branch most directly accountable to the people. Article I is, by a vast margin, the longest and most detailed of the original articles, a testament to its perceived importance. It was here that the Great Compromise was forged, creating a bicameral Congress to balance the interests of the populous states and the small states, a brilliant stroke of political engineering that saved the Convention from collapse.
