BASSA, a province of the British protectorate of Northern Nigeria, occupying the angle made by the meeting of the Benue river with the Niger.
The districts which now comprise the province of Bassa came nominally under British control in 1900, but up to the year 1903 administrative authority was confined to the western half with Dekina (in 7° 3' E., 7° 41' N.) for its capital.
The slave-trade is still alive in this district, and an overland route for slaves is believed to have been established through eastern Bassa to the Benue.
The best known in this section are the three Baksan passes of Chiper (io,800 and 10,720 ft.), Bassa (9950 ft.) and Donguz-orun (10,490 ft.), south of Elbruz; those of Becho (11,070 ft.), Akh-su (12,465 ft.), Bak (10,220 ft.), Adyr-su (12,305 ft.) and Bezingi (10,090 ft.), between Elbruz and Dykh-tau; and those of Shari-vizk (11,560 ft.), Edena, Pasis-mta or Godivizk (11,270 ft.), Shtulu-vizk (10,860 ft.), Fytnargyn (11,130 ft.), between Dykh-tau and Adai-khokh; the Bakh-fandak (9570 ft.), between Adai-khohk and Kasbek; and the two Karaul passes (11,680 and 11,270 ft.) and Gurdzi-vizk (10,970 ft.), connecting the valley of the Urukh with that of the Rion.
For administrative purposes the territories were at first divided into seventeen provinces: Sokoto, Gando, Kano, Katsena, Bornu East, Bornu West, Zaria, Bauchi, Borgu, Kontagora, Nassarawa, Muri, Yola, Bassa, Kabba, Illorin, Nupe.
