'The Main Plot' was a conspiracy by
English Catholics, allegedly led by lay Catholic
Henry Brooke, Lord Cobham, to remove King
James I of England from the English throne, replacing him by aid of
Spain with his cousin
Arabella (or Arbella) Stuart.
The plot involved
George Brooke and Lord Grey of
Wilton raising a regiment and marching on
London to take over the government. Henry Brooke, 8th Lord Cobham, was to act as a negotiator. In the version of the plot presented at trial, Cobham was negotiating with the court of
Aremberg to contact the
Spanish court for a very large sum of money (approximately one-hundred and sixty thousand pounds). He was to travel to
Brussels, then to Spain, collect the money, and go back to
England via
Jersey, where
Walter Raleigh was governor. Raleigh and Cobham were then to divide up the money and decide how best to spend it in furtherance of sedition.
The plot was discovered by questioning prisoners arrested in connection with the
Bye Plot. In particular,
George Brooke, brother of Lord Cobham, had been involved in the Main plot (or "the treason at
Maine"). He apparently believed that he could bolster his position by informing on his brother. It is currently considered unlikely that Walter Raleigh had any culpability in the plot; see the biography of Raleigh's prosecutor,
Edward Coke.
If George Brooke thought that informing on his brother would help him in his show trial for the
Bye plot, he was wrong as Brooke was executed with the other Bye plot conspirators in
1603. Cobham, too, was executed for his involvement in the Main plot in
1618. Raleigh was imprisoned in the
Tower of London for thirteen years and was eventually released, although he was himself executed in 1618.
