Iaselnichii

(equerry), a court rank and post in the palace administration and government of Russia from the 15th to late 17th centuries. In the 15th and 16th centuries, the iasel’nichii was the chief assistant to the koniushii (senior equerry). After changes in the system of palace management, including the abolition of the position of koniushii in the 17th century, the iasel’nichii became the head of the Koniushennyi Prikaz (Equerry Office), which was in charge of the tsar’s horses and hunting parties. In the 16th century, the iasel’nichie were members of the Boyar Duma.
