As soon as the first [[BattleMechs]] began to dominate the battlefields of the twenty-fifth century, the humans that piloted these awesome machines began to gain a power and influence well-beyond other soldiers on the field. An entire social class soon formed around those who piloted these increasingly important war machines. These so-called [[MechWarrior| MechWarriors]], the modern incarnation of knights, were given the monumental task of defending their homelands and their rulers. As with the middle ages of Europe on ancient [[Terra]], these MechWarriors were made knights, given honors and some even bestowed royal titles, conveying authority over entire worlds and more. This romantic image of the MechWarrior -knight has eroded somewhat over the past few decades, but it remains strong in the hearts of the [[Inner Sphere]]'s people.

It was not uncommon that a 'Mech might be centuries-old with numerous repairs and replacements. That custom changed radically following the conclusion of the [[Fourth Succession War]].

Consequently, House militaries own most new 'Mechs in service in the Inner Sphere in the post-Fourth Succession War period. Among the [[Clans]], all property belongs to the Clan and so a Clansman MechWarrior never owns his 'Mech.
