Like Upper Canada, there was political unrest and a rebellion challenged the British rule of the predominantly French population. After the Patriote Rebellion was crushed by the British army and Loyal volunteers, the 1791 Constitution was suspended on March 27, 1838 and a special council was appointed to administer the colony.
The provinces of Lower Canada and Upper Canada were combined as the United Province of Canada in 1841, when the The Union Act came into force. Their separate legislatures were combined into a single parliament with equal representation for both constituent parts.[1]

Constitution of Lower Canada in 1791
The Province of Lower Canada inherited the mixed set of French and English institutions that existed in the Province of Quebec during the 1763-1791 period and which continued to exist later in Canada-East (1841-1867) and ultimately in the current Province of Quebec (1867-).
