The Russian Tradition of The Knights Hospitaller (the Order of Knights of the Hospital of St. John of Jerusalem or Knights of Malta or Knights of Rhodes) are a continuous tradition of the Order of St. John. Their distinction emerged when the Mediterranean stronghold of Malta was captured by Napoleon in 1798 when he made his expedition to Egypt. As a ruse, Napoleon asked for safe harbor to resupply his ships, and then turned against his hosts once safely inside Valletta. Grand Master Ferdinand von Hompesch failed to anticipate or prepare for this threat, provided no effective leadership, and readily capitulated to Napoleon. This was a terrible affront to most of the Knights desiring to defend their stronghold and sovereignty. The Order continued to exist in a diminished form and negotiated with European governments for a return to power. The Emperor of Russia gave the largest number of Knights shelter in St Petersburg and this gave rise to the Russian tradition of the Knights Hospitaller and recognition within the Russian Imperial Orders. In gratitude the Knights declared Ferdinand von Hompesch deposed and Emperor Paul I was elected as the new Grand Master. The continuous Order was also approved by the Papacy, but due to British fear of Russian taking presence in the Mediterranean and because many knights were Orthodox the Order became de facto the traditional Order but de jure not recognised similar or at par with the formation of the 19th-century Sovereign Military Order of Malta (SMOM).
Blessed Gerard created the Order of St John of Jerusalem as a distinctive Order from the previous Benedictine establishment of Hospitallers (Госпитальеры). It provided medical care and protection for pilgrims visiting Jerusalem. After the success of the First Crusade, it became an independent monastic order, and then as circumstances demanded grafted on a military identity, to become an Order of knighthood. The Grand Priory of the Order moved to Rhodes in 1312, where it ruled as a sovereign power, then to Malta in 1530 as a sovereign/vassal power.
