Mace Windu was very talented and powerful with the Force and he passed his Jedi Knight trials earlier than normal. He speeded through the ranks of the Jedi Order, becoming Jedi Master at 28, and was appointed to the Jedi Council eventually becoming Master of the Order second only to Grand Master Yoda.
When Jedi Knight Obi-Wan Kenobi was captured on Geonosis, Mace Windu accompanied the assault force of Jedi and clones that would assault the planet. During the small skirmish that started the battle, before the clones arrived, Windu had nearly captured Count Dooku when Jango Fett came after him and Mace was forced to kill him. During the remainder of the war Windu was a High Jedi General and in charge of many fronts of the war.
He served as a General during the war including through some of the more important battles that helped turn the tide for the Republic's favor. On Ryloth he was able to bring an underground force and politicians see eye to eye in order to beat back the Separatists and regain an important planet. When a Jedi holocron was stolen Mace was apart of the Jedi team in charge of defending the Jedi temple as well as interrogating those responsible.
Near the end of The Clone Wars the Jedi Council finally became aware of the Sith threat facing them and the Republic. Mace Windu was among the Jedi to confront Supreme Chancellor Palpatine, who was Darth Sidious. In the ensuing duel all the Jedi were killed except Windu who had cornered and all but defeated the Sith Lord when Anakin Skywalker arrived. Confused and confronted with a choice Skywalker choose the path of the dark side and gave Darth Sidious the chance to kill Mace Windu.
Windu was a very cautious Jedi, slow to trust other people including other Jedi. Despite the cation Mace is a very courageous warrior especially in battle and is one of the more power full of Jedi.
Mace Windu is the only Jedi known to have a lightsaber thats not Red, Blue, or Green. When Samuel L. Jackson was casted to play the role in the Star Wars prequels he requested from George Lucas a purple colored lightsaber. Jackson said it was so he could always see himself in a crowd of Jedi and to look badass of course.
In story Mace Windu at the age of 14 was worrying the Jedi Council because he still couldn't construct his own lightsaber that he had envisioned in his own dreams. After requesting the council challenge him to allow him to do this the council agreed and sent him to his home world of Hurikane. While on his mission Windu had learned a valuable lesson after accidentally hurting one of the natives. After he restored the native to full health using the Force they rewarded him with a special lightsaber crystal that was purple. This was the crystal he would use to construct his own lightsaber with giving him his distinct violet blade.
