  Most of the Imperial and French fiefs in what is now the Netherlands and Belgium were united in a personal union by Philip the Good in 1433. The House of Valois-Burgundy and their Habsburg heirs would rule the Low Countries from 1384 to 1581. The new rulers defended Dutch trading interests. The fleets of the County of Holland defeated the fleets of the Hanseatic League several times. Amsterdam grew and in the 15th century became the primary trading port in Europe for grain from the Baltic region. Amsterdam distributed grain to the major cities of Belgium, Northern France and England. This trade was vital because Holland could no longer produce enough grain to feed itself. Land drainage had caused the peat of the former wetlands to reduce to a level that was too low for drainage to be maintained.
  
  Under Habsburg Charles V, all fiefs in the current Netherlands region were united into the Seventeen Provinces, which included most of present-day Belgium, Luxembourg, and parts of France and Germany. In 1568, under Phillip II, the Eighty Years' War between the Provinces and their Spanish ruler began. The level of ferocity exhibited by both sides can be gleaned from a Dutch chronicler's report:
  
  On more than one occasion men were seen hanging their own brothers, who had been taken prisoners in the enemy's ranks... A Spaniard had ceased to be human in their eyes. On one occasion, a surgeon at Veer cut the heart from a Spanish prisoner, nailed it on a vessel's prow, and invited the townsmen to come and fasten their teeth in it, which many did with savage satisfaction.
  
  The Duke of Alba attempted to suppress the Protestant movement in the Netherlands. Netherlanders were "burned, strangled, beheaded, or buried alive" by his " Blood Council " and Spanish soldiers. Bodies were displayed along roads to terrorise the population into submission. Alba boasted of having executed 18,600; this figure does not include those who perished by war and famine.
  
  The first great siege was Alba's effort to capture Haarlem and thereby cut Holland in half. It dragged on from December 1572 to the next summer, when Haarlemers finally surrendered on 13 July upon the promise that the city would be spared from being sacked. It was a stipulation Don Fadrique was unable to honour, when his soldiers mutinied, angered over pay owed and the miserable conditions of the campaign. On 4 November 1576, Spanish tercios seized Antwerp and subjected it to the worst pillage in the Netherlands' history. The citizens resisted but were overcome; seven thousand were killed and a thousand buildings were torched.
  
  Following the sack of Antwerp, delegates from Catholic Brabant, Protestant Holland and Zeeland agreed to join Utrecht and William the Silent in driving out Spanish troops and forming a new government for the Netherlands. Don Juan of Austria, the new Spanish governor, was forced to concede initially, but within months returned to active hostilities. The Dutch looked for help from the Protestant Elizabeth I of England, but she initially stood by her commitments to the Spanish in the Treaty of Bristol of 1574. When the next large-scale battle occurred at Gembloux in 1578, the Spanish forces won easily. In light of the defeat at Gembloux, the southern states of the Seventeen Provinces distanced themselves from the rebels in the north with the 1579 Union of Arras. Opposing them, the northern half of the Seventeen Provinces forged the Union of Utrecht in which they committed to support each other against the Spanish. The Union of Utrecht is seen as the foundation of the modern Netherlands.
  
  Spanish troops sacked Maastricht in 1579, killing over 10,000 civilians. In 1581, the northern provinces adopted the Act of Abjuration, the declaration of independence in which the provinces officially deposed Philip II. Against the rebels Philip could draw on the resources of the Spanish Empire. Elizabeth I sympathised with the Dutch struggle and sent an army of 7,600 soldiers to aid them. English forces faced the Spanish in the Netherlands under the Duke of Parma in a series of largely indecisive actions that tied down significant numbers of Spanish troops and bought time for the Dutch to reorganise their defences. The war continued until 1648, when Spain under King Philip IV recognised the independence of the seven north-western provinces in the Peace of Münster. Parts of the southern provinces became de facto colonies of the new republican-mercantile empire.
