Until this point, many influential leaders in Pennsylvania had not supported independence from the Crown, but had favored reconciliation. The Continental Congress, however, inspired the more radical elements in Pennsylvania to overmaster these more conservative leaders. Shortly afterwards, in June 1776, these committees called a state convention, which met on July 15, 1776. The decisions made at that convention would, when ratified, cause the previous government to be completely superseded; it established a Council of Safety to rule in the interim, and it drew up the commonwealth (state) constitution, which was adopted on September 28, 1776. The change of government, was, however, opposed by many of the commonwealth's citizens - John Dickinson,
James Wilson,
Robert Morris, and
Frederick Muhlenberg, among others. The main goal of this new constitution was not only to limit but to completely prevent the creation of an aristocracy, as many radicals, "employed a brand of rhetoric laden with appeals to patriotism and bromides against the British Empire." Specifically, it was based on
Thomas Paine's
Common Sense. It played a major role in the rewriting of this constitution. According to many sources, Paine "played a conspicuous part." This fear can be seen in the amount of emphasis placed on terms like "liberty" and "the people's government." In the new constitution, the lower class would wield a much larger amount of power than they had ever had access to. Additionally, the unicameral legislature had been added for the same purpose. The framers believed that adding an upper house would lead to the creation of an aristocracy down the line.
Thomas Wharton Jr., who had been the President of the Committee of Safety, was chosen as President of the Supreme Executive Council in June 1777 and became, in effect, the first Governor of the Commonwealth. ==Innovations==
