The CMS Silicon Strip Tracker, with its 9.3 million readout channels and an area of 198m², is the most complex device of its kind ever operated. This talk will give an overview of the history of this detector, from the construction to the latest results.

The construction of this device required an unprecedented effort of a large community of institutes, with a high quality assurance standard. After the integration in the CMS experiment in 2008, the Strip Tracker was commissioned using dedicated internal calibration procedures and then tuned using cosmic rays and finally also proton-proton collisions. The performance was also studied using data from collisions: data integrity, noise, hit finding efficiency, alignment, signal calibration and track reconstruction have been measured with the data and show an excellent agreement with the expected performance.
