The alternate name of the fanbase and territory of the San Francisco 49ers. The original being the 49er Faithful. The origins are believed to be inspired by John Madden once calling the 49er dynasty of the 80's "the Holy Roman Empire of the NFL." SF Bay Area writers also referred to the 49ers fans as "the Niner Empire" to oppose the Raider Nation. The Niner Empire name was adopted by a group of diehard Northern California fans during the down years of the mid 2000's, and has grown in popularity since its' inception. It is made up of various factions of fans from all over the US, and even worldwide. Demographically, it is all encompassing, though one thing remains the same: they are all fiercely loyal to the 49ers, known for their predilection towards rowdiness and general belligerency, especially to rivals teams and fans.
The stereotype of San Francisco fans being soft, wine 'n cheese snobs has been destroyed by the Niner Empire, the loyal, proud, and hostile fans of the 49ers.

Only the most diehard, faithful 49ers fans may call themselves part of the Niner Empire.
