Special relativity is always applicable, but only really useful when you are considering objects moving close to the speed of light.
General relativity should be used when objects are very heavy or dense.
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.
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.
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. Please visit http://physics.ucr.edu/~wudka/Physics7/Notes_www/node47.html for more information about Galilean 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.

E=mc^2 Edit : That equation is part of "special relativity" not "general relativity".
