Lando (also known as Landus) was Pope from c. September 913 to his death c. March 914. His short pontificate fell during an obscure period in papal and Roman history, the so-called Saeculum obscurum (904–964). He was the last pope to use a papal name (in his case, his birth name) that had not been used previously until the election of Pope Francis in 2013.
According to the Liber pontificalis, Lando was born in the Sabina, and his father was a wealthy Lombard count named Taino from Fornovo. The Liber also claims that his pontificate lasted only four months and twenty-two days. A different list of popes, appended to a continuation of the Liber pontificalis at the Abbey of Farfa and quoted by Gregory of Catino in his Chronicon Farfense in the twelfth century, gives Lando a pontificate of six months and twenty-six days. This is closer to the duration recorded by Flodoard of Reims, writing in the tenth century, of six months and ten days. The end of his pontificate can be dated to between 5 February 914, when he is mentioned in a document of Ravenna, and late March or early April, when his successor, John X, was elected.
Lando is thought to have been the candidate of Theophylact I, Count of Tusculum, and his wife, Theodora, who were the most powerful persons in Rome at the time. The Theophylacti controlled papal finances through their monopoly of the office of vestararius, and also controlled the Roman militia and Senate. During Lando's reign, Arab raiders, operating from their stronghold on the Garigliano river, destroyed the cathedral of San Salvatore in Vescovio in his native diocese. No document of Lando's chancery has survived. The only act of his reign that is recorded is a donation to the diocese of Sabina mentioned in a judicial act of 1431. Lando made the large personal gift in order to restore the cathedral of San Salvatore so that the clergy who were then living at Toffia could return.
