Siege of Thessalonica (1422–1430)

The siege of Thessalonica between 1422 and 1430 saw the Ottoman Empire under Sultan Murad II capture the city of Thessalonica. Thessalonica remained in Ottoman hands for the next five centuries, until it became part of the Kingdom of Greece in 1912.

Thessalonica had already been under Ottoman control from 1387 to 1403 before returning to Byzantine rule in the aftermath of the Battle of Ankara. In 1422, after the Byzantines supported Mustafa Çelebi as a rival pretender against him, Murad attacked Thessalonica. Unable to provide manpower or resources for the city's defense, its ruler, Andronikos Palaiologos, handed it over to the Republic of Venice in September 1423. The Venetians attempted to persuade the Sultan to recognize their possession, but failed as Murad considered the city his by right and the Venetians to be interlopers. This impasse led to an Ottoman blockade of Thessalonica, which occasionally flared up with direct attacks on the city. At the same time, the conflict was mostly fought as a series of raids by both sides against the other's territories in the Balkans and the Aegean islands. The Venetians repeatedly tried to apply pressure by blocking the passage of the Dardanelles at Gallipoli, with little success.

The blockade quickly reduced the inhabitants to near starvation, and led many to flee the city. The restrictions placed on them by the siege, the inability of Venice to properly supply and guard the city, the violations of their customary rights, and rampant profiteering by Venetian officials led to the formation of a pro-surrender party within the city, which gained strength among the inhabitants. The city's metropolitan bishop, Symeon, encouraged his flock to resist. However, by 1426, with Venice's inability to secure peace on its own terms evident, a majority of the local population had come to prefer a surrender to avoid the pillage that would accompany a forcible conquest. Venice's efforts to find allies against the Ottomans also failed: the other regional potentates either pursued their own course, were themselves antagonistic to the Venetians, or were defeated by the Ottomans.

After years of inconclusive exchanges, the two sides prepared for a final confrontation in 1429. In March, Venice formally declared war on the Ottomans, but even then the conservative mercantile aristocracy running the Republic were uninterested in raising an army sufficient to protect Thessalonica, let alone to force the Sultan to seek terms. In early 1430, Murad was able to concentrate his forces against Thessalonica, taking it by storm on 29 March 1430. The privations of the siege and the subsequent sack reduced the city to a shadow of its former self, from perhaps as many as 40,000 inhabitants to c. 2,000, and necessitated large-scale resettlement in the following years. Venice concluded a peace treaty with the Sultan in July, recognizing the new status quo. Over the next few decades, the antagonism between Venice and the Ottomans morphed into a rivalry over control of Albania.

Thomas Rotherham

Thomas Rotherham (24 August 1423 – 29 May 1500), also known as Thomas (Scot) de Rotherham, was an English cleric and statesman.

He is considered a venerable figure in Rotherham, South Yorkshire, his town of birth.

William Herbert, 1st Earl of Pembroke (died 1469)

William Herbert, 1st Earl of Pembroke KG (c. 1423 – 27 July 1469), known as "Black William", was a Welsh nobleman, politician, and courtier. He was the son of William ap Thomas, founder of Raglan Castle, and Gwladys ferch Dafydd Gam, and grandson of Dafydd Gam, an adherent of King Henry V of England.

His father had been an ally of Richard of York, and Herbert supported the Yorkist cause in the Wars of the Roses. In 1461 Herbert was rewarded by King Edward IV with the title Baron Herbert of Raglan (having assumed an English-style surname in place of the Welsh patronymic), and was invested as a Knight of the Garter.

Soon after the decisive Yorkist victory at the Battle of Towton in 1461, Herbert replaced Jasper Tudor as Earl of Pembroke which gave him control of Pembroke Castle. However, he fell out with Lord Warwick "the Kingmaker" in 1469, when Warwick turned against the King. William and his brother Richard were executed by the Lancastrians, now led by Warwick, after the Battle of Edgecote Moor, near Banbury.Herbert was succeeded by his son, William, but the earldom was surrendered in 1479. It was later revived for a grandson, another William Herbert, the son of Black William's illegitimate son, Sir Richard Herbert of Ewyas.
