The first known person to theorize about relativity was Galileo, who articulated the first "relativity principle" in the seventeenth century. In generating his relativity principle, Galileo removed the distinction between stationary and moving observers, arguing that people on earth cannot tell if they are really at rest or if they are moving with the rotation of the earth each day. To demonstrate this, Galileo used the example of a cannonball falling from the top of a ship's mast. He noted that the cannonball will land at the base of the mast whether the ship is moving steadily through the ocean, or whether it is at rest in a dock. Even if they observe the falling ball, people on the ship cannot tell if they are really at rest or if they are moving with the ship. They cannot distinguish their state of rest from the ship's state by observing motion that takes place within the "reference frame" of the ship. In other words, a person at rest on the deck of a ship cannot determine whether the ship is at rest or moving at a steady speed through the ocean by observing actions that happen on the ship itself. That person must observe the ship relative to its surrounding environment in order to make such a determination.
Galilean Relativity - Galileo Galilei Special and General Relativity - Albert Einstein
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.
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.
Albert Einstein discovered the theory of relativity
The Theory of Special Relativity was published in 1905. General Relativity was published in 1915.

The theorizer of relativity would be Albert Einstein. Einstein's theory of relativity consisted of special relativity and general relativity. It has to do with relative measurements of quantities to observes, like space contracts and time dilates. Space time was a concept of relativity. The speed of lights invariance was also a part of the theory.

Galilean relativity asserts that the passage of time is the same for all observers. Einsteinian relativity does not claim universal time for all observers. Instead, it asserts that the speed of light and the fundamental laws of physics are the same for all observers.
Galileo Galile wrote "the Theory of Relativity", and Einstein wrote the General theory of relativity and the special theory of relativity.
Albert Einstein published the works now referred to as Special Relativity in 1905 and General Relativity in 1916.

A Theory of Relativity was created in 2001.
The Theory of Relativity was developed by Albert Einstein.
