Threats to the rule of Henry VII.

• Trouble broke out whilst Henry was on a royal progress to York, where Yorkist support still remained strong.
• Lord Lovell and the two Stafford brothers planned to ambush the King.
• This attack failed as Henry heard of the plans against him and sent a royal army.
• However, this rising plays some significance as it occurred within a year of Henry's usurpation, demonstrating his vulnerability on the throne. 

In 1486, Lambert Simnel began to pretend to be Edward, Earl of Warwick, whom Henry had imprisoned in the Tower.

Significance:

• This was a serious threat as it occurred within a year of Henry's usurpation of the throne, demonstrating the vulnerability of his position.
• Lambert Simnel had support based in Ireland and Oxford.
• Margaret of Burgundy provided Simnel with 2000 mercenaries. 
• Henry's vulnerable position is further indicated by the fact that he did not hear of the threat until 1487.
• Henry offered a pardon, but the rebels rejected it.
• The rebels rallied the support of the Earl of Lincoln.
• The rebels met Henry's army at the Battle of Stoke in June 1487.
• The rebels were easily defeated. However, the fact that a weak claimant to the throne managed to rally support and bring the King to battle demonstrates the vulnerability of his position. 

• This was a result of Henry's attempts to raise money to fund Brittany in its struggle against France.

Perkin Warbeck pretended to be Richard, Duke of York, whose death with assumed but never confirmed. 

• In 1492, he received support from the French. However, the signing of the Treaty of Etaples seized this support.
• In 1493, he was welcomed into Burgundy. Consequently, Henry VII broke off the cloth trade with Antwerp.
• 1494, Warbeck was recognised by the Holy Roman Emperor Maximillian.
• In 1495, he was welcomed into Scotland by James IV. In 1497, he married James IV's cousin. Yet, in the same year, the Truce of Ayton was established and Warbeck was forced to flee.
• He was captured and imprisoned in the Tower. In 1499, he was executed.

This threat was extremely significant due to the fact that it took Henry eight years to finally capture Warbeck and end the threat. Furthermore, the foreign support Warbeck received implies that Henry was not recognised as the rightful King in many European countries. 

In 1495, Henry executed Sir William Stanley after discovering he had provided support for the Perkin Warbeck plot. 

In 1497, the Cornish rebelled over increasing taxes to fund a campaign in Scotland.

Significance:

• There were over 15,000 rebels.
• They threatened London.

• By 1506, Henry had almost removed all threats to his position as King.
• Only the Earl of Suffolk remained, who lived in exile in Burgundy.
• Fortunately, Phillip of Burgundy was forced to take refuge in England due to a storm, and so Henry was able to pressurise him into handing over Suffolk.
• He was imprisoned in the Tower.
