Membership
Every Russian Grand Duchess was conferred the Grand Cross of the Order at her christening, and Princesses of the Imperial Blood were invested upon attaining their majority at 18. In addition to the royal members, a fixed number of other members were permitted by the statutes:
12 Dames Grand Cross
94 Dames Small Cross
The 12 Dames Grand Cross were typically female members of foreign ruling houses. Queen Alexandra of Great Britain was made a Dame Grand Cross of the Order of Saint Catherine by Alexander II, and Princess Alice of Greece was also a member of the Order. The only known award of the order to a male was in 1727 to then 13-year-old prince Alexander Menshikov, son of Aleksandr Danilovich Menshikov, closest friend of Emperor Peter I of Russia. The Dames Small Cross were all women of the highest nobility, who were part of the suite of the Empress and had engaged in important philanthropic or charitable works outside of their duties at Court.
Annual function
The Order of Saint Catherine's annual function was held on, the feast day of Saint Catherine of Alexandria. The Order met for a celebration of the Divine Liturgy. Then, wearing the robes and the insignia of the Order, the women of the Imperial Family, followed by the 106 Dames Grand and Small Cross would go in procession from the Imperial Chapel to a banqueting hall specially prepared for the occasion. The Hall of Saint Catherine in the Great Kremlin Palace in Moscow was used for these occasions. The coloring and decoration of the hall incorporate those of the Order. The hall also served as the throne room for the Empress Consort. To this day, in the Russian Federation uses this room to receive foreign dignitaries.
