Garibi or Garipler were one of the four subdivisions of Kapikulu Sipahi cavalry in the Ottoman Army. Numbering about 1,000, originally they were not devshirmeh like janissaries, or Turkic landowners like the rest of Kapikulu Sipahis. Instead, they were generally Turks, Moors, or renegade Christians, who having followed adventures, and being poor and seeking fortune, arrived at the rank of horse guards to the sultan. Their pay was 12 aspers (about one-tenth of a piastre) per day. But in classical period, the name became almost symbolic and most of the garibs became recruited from sons of Turkish aristocrats and high-ranking officers, like the most of the Kapikulu Sipahis.
The word garibii signifies poor, and stranger.
