Rainier, Marquess of Montferrat

From Wikipedia, the free encyclopedia

For Rainier's descendant of the same name, see Renier of Montferrat.

Renier or Rainier (Italian: Ranieri; c. 1084 – May 1135) was the Margrave of Montferrat from around 1100 to his death. He was the son of William IV and his wife Otta d'Agliè, a daughter of Tibaldo d'Agliè.

Renier was a powerful lord in his own time, appearing extensively in the contemporary documentation. With him the Aleramici of Montferrat first begin to throw off the shroud of obscurity and demonstrate a degree of influence in Italian politics. The beginning of his reign, nevertheless, is not clearly known, as he first appears in a document of 23 March 1111 as Raynerius de Monteferrato marchio. He appears with this same title years later in 1126 and 1133 when, with other members of his family, he founded the Cistercian monstery of Santa Maria di Lucedio near Trino.

Around the time of his appearance in the pages of history, c. 1111, Renier was a follower of the Emperor Henry V. In that year he obtained an imperial concession for the citizens of Turin: a diploma regarding the Via Francigena which passed through the town. Also that year, with his cousin Oberto I of Occimiano, he donated to the Chapter of Saint Evasius of Casale the church of San Martino di Zenzano infra castrum Aucimianum (in the castle of Occimiano). That this act took place in Occimiano testifies to the importance of that locality, which had in the past been the seat of kings.

In 1113, Renier donated his portion of the Langiano to the monastery of San Secondo di Terra Rossa, affiliated with the Abbey of Fruttuaria. On 23 May 1116, Renier was present with the Emperor when the latter bestowed the castles of Celle, Frassinello, Fubine, and Cuccaro on his nephew Conrad and Guido Cane.

[edit] Family

In 1105, Renier married Gisela, daughter of William I, Count of Burgundy, already the widow of Humbert II of Savoy and mother of Adelaide of Maurienne, who, in 1115, became the second queen of Louis VI of France. She and Renier had three or four daughters:

  • Joanna, who married William Clito, Count of Flanders, in 1127, and was widowed a year later
  • Matilda, who married Alberto Zueta, Margrave of Parodi
  • Adelasia, who became a nun
  • one possibly named Isabella, who married Guido, Count of Biandrate (although it is possible that this may be a second marriage of Joanna)

They also had a son, William, who succeeded to the march.
