Einstein's theory of relativity encompasses two theories: special relativity and general relativity. The theory of relativity is simply referred to as relativity in the field of physics.
Galilean Relativity - by Galileo Galilei Special Relativity and General Relativity - by Albert Einstein
The word relativity is a noun. Relativity is a principle in Physics.
"Relativity" is a noun. For instance: Relativity is a wonderful concept.
The scientific Theories of General and Special Relativity were first proposed by Albert Einstein.Special Relativity in 1906 and General Relativity in 1916.
Galileo Galile wrote "the Theory of Relativity", and Einstein wrote the General theory of relativity and the special theory of relativity.

Galilean Relativity - Galileo Galilei Special and General Relativity - Albert Einstein
The Theory of Special Relativity was published in 1905. General Relativity was published in 1915.
There was two kinds of theory of relativity, the special relativity was published in 1905, and the final form of the general relativity was published in 1916.
When speaking of Relativity, people mostly think of Albert Einstein. However, Relativity was experimented by Galileo Galilei first. So when speaking of Relativity, it helps to be specific: Einsteinian Relativity or Galilean Relativity.
E=mc^2 Edit : That equation is part of "special relativity" not "general relativity".
