Anti-federalists intended to have bill of rights included in the constitution.
Federalists desired to have a strong federal government while anti federalists intended that the states be conferred with unlimited powers. Anti-federalists had their own apprehensions and feared that constitution may have any despotic element as an impact of British colonial imperialism that existed prior to declaration of Independence.
So anti federalists stated that they need to incorporate bill of rights in the constitution. Initially federalists protested saying that it is impossible to state every right and some unstated right may be abused and broken.
