Piattoli, Potocki and Poniatowski begun to reach a consensus on a more constitutional monarchy approach, and started to draft a constitutional document. Overall, the first two years of the Sejm passed with few major reforms, and it was the second half of the Sejm duration that brought major changes. 1791–92 The elections of autumn 1790 resulted in a new group of deputies joining those already elected. A second Marshal of the Sejm was elected (Kazimierz Nestor Sapieha). As Małachowski was seen as associated with the reformers, Sapieha was initially seen as a conservative, although he would later switch sides and join the reformers. The doubled number of deputies exceeded the capacity of the parliament chambers, and not all of the deputies could secure a seat; public interest also grew and the entire building and the observation galleries were often overcrowded. While the Sejm comprised representatives only of the nobility and clergy, the reformers were supported by the burghers (townspeople), who in the fall of 1789 organized a Black Procession, demonstrating their desire to be part of the political process. Taking a cue from similar events in France, and with the fear that if burghers' demands were not met, their peaceful protests could turn violent, the Sejm on 18 April 1791 adopted a law addressing the status of the cities and the rights of the burghers (the Free Royal Cities Act). Together with the legislation on the voting rights (the Act on Sejmiks of 24 March 1791), it became incorporated into the final constitution. The new Constitution had been drafted by the king, with contributions from others, including Ignacy Potocki and Hugo Kołłątaj. The king is credited with authoring the general provisions, and Kołłątaj, with giving the work its final shape. Poniatowski aimed for a constitutional monarchy similar to the one in England, with strong central government based upon a strong monarch. Potocki wanted to make the parliament (Sejm) the most powerful of the state's institutions, and Kołłątaj, for a "gentle" social revolution, enfranchising other classes in addition to the till-then dominant nobility, but doing so without a violent overthrow of the old order. Reforms were opposed by conservative elements, including the Hetmans' Party. The reform's advocates, threatened with violence from their opponents, managed to move debate on the new constitution forward by two days from the original 5 May, while many opposed deputies were still away on Easter recess.
