Twice in thirty years Panama broke those who reached for it. In 1671 the buccaneer Henry Morgan crossed the jungle and burned Panamá Viejo. In 1698-1700 Scotland staked a large share of its wealth on a Darién colony where about two thousand died, a failure that helped push Scotland toward the 1707 Act of Union.
Historians disagree on who burned Panamá Viejo, Morgan's men or the Spanish governor, and on whether Morgan knew of the Treaty of Madrid. Darién was a major catalyst for the Union but not its sole cause, and estimates of the share of Scottish capital invested range from 20 to 40 percent.
