The Órder of the Band, Knights of the Band, or Equites Bindae, were a military order in Spain, instituted by Alfonso XI, King of Castile in 1332. It takes its name from the banda, band, sash or red ribbon which came across over the right shoulder and under the left arm of the knight.
The order was awarded to certain distinguished knights and squires of the king, and has roots back as far as 1324. This order was for none but nobles; the eldest sons of grandees were excluded; and a prerequisite to admittance was to have served at least ten years either in the army, or at court. They were bound to take up arms for Catholicism against infidels. The King himself was Grand Master of the order. After a period of decline it is considered to have been extinct by 1474.
