Why did states want written constitutions?
States wanted written constitutions for two main reasons. First, a written constitution would spell out the rights of all citizens. Second, it would set limits on the power of the government.
How did the constitutions of the territories that applied for statehood differ from the constitutions of most Eastern states?
Written constitutions are set out in an actual document (e.g. United States, France). Unwritten constitutions are a collection of traditions that may or may not be written out in a single, coherent document--often they are amalgamations of numerous documents over long periods of time combined with rules that courts have developed over time (e.g. United Kingdom).
