The formal signing ceremony took place on the evening of 28 November 2022 in front of Nigerian royalty and other dignitaries. History Social context and creation Many of the dramatic sculptures date to the thirteenth century, and a large part of the collection dates to the fifteenth and sixteenth centuries. It is believed that two "golden ages" in Benin metal workmanship occurred during the reigns of Esigie (fl. 1550) and of Eresoyen (1735–1750), when their workmanship achieved its highest quality. The Kingdom of Benin, which occupied southern parts of present-day Nigeria between the fourteenth and nineteenth centuries, was rich in sculptures of diverse materials, such as iron, bronze, wood, ivory and terra cotta. The Oba's palace in Benin City, the site of production for the royal ancestral altars, also was the backdrop for an elaborate court ceremonial life in which the Oba of Benin, his warriors, chiefs and titleholders, priests, members of the palace societies and their constituent guilds, foreign merchants and mercenaries, and numerous retainers and attendants all took part. The palace, a vast sprawling agglomeration of buildings and courtyards, was the setting for hundreds of rectangular brass plaques whose relief images portray the persons and events that animated the court. Bronze and ivory objects had a variety of functions in the ritual and courtly life of the Kingdom of Benin. They were used principally to decorate the royal palace, which contained many bronze works. They were hung on the pillars of the palace by nails punched through them. As a courtly art, their principal objective was to glorify the Oba, the divine king, and the history of his imperial power or to honour the Iyoba of Benin (the queen mother). Art in the Kingdom of Benin took many forms, of which bronze and brass reliefs and the heads of kings and queen mothers are the best known. Bronze receptacles, bells, ornaments, jewellery, and ritual objects also possessed aesthetic qualities and originality, demonstrating the skills of their makers, although they are often eclipsed by figurative works in bronze and ivory carvings. In tropical Africa the technique of lost-wax casting was developed early, as the works from Benin show.
