Best answer for filling in that blank: EQUALITY
Freedom means that individuals have liberty to have their own beliefs, their own lives, without being controlled or dominated by the government or by others in the country who have different beliefs.
Equality means each individual is to have the same rights within the country, so that there is equal justice for all citizens. Every person is to be treated the same way under the laws of the land.
Note that the French Revolution also took up these themes of liberty and equality, to which they added also "fraternity" (brotherhood) as a third ideal for the government and nation they wished to form.
