In the late 1640s the Levellers proposed a new constitution?

In the late 1640s, the Levellers, a political movement arising during the English Civil War, proposed a new constitution aimed at establishing a more egalitarian society. Their "Agreement of the People" called for universal suffrage, religious freedom, and a representative government accountable to the people. The Levellers sought to dismantle the existing aristocratic structures and empower common citizens, reflecting their radical vision of democracy and individual rights. However, their ideas faced opposition from both the monarchy and more conservative factions within the Parliament.
