Boyaca

Boyaca is a department of Colombia, one of the original nine states of the "United States of Colombia".

Boyaca is centrally located within Colombia, almost entirely within the mountains of Eastern Cordillera[?], although the western end of the department extends to the Magdalena River[?] at the town of Puerto Boyaca[?]. It has an area of 23,102 sq km (8,880 sq mi). The capital city is Tunja[?].

Although Boyaca had the right to issue its own postage stamps, it used the stamps of Colombia until 1902, when it issued a stamp honoring Diego Mendoza Perez[?]. It issued a few more, the last coming in 1904. The stamps themselves remain commonly available, but authentic uses on cover are rare.
