Dobra Pé Terra - Fernando I Lisboa mint

Fernando I came to the throne in 1367 inheriting a treasury strained by his father Pedro I's domestic policies, and almost immediately embroiled Portugal in the first of three costly wars with Castile. The Lisboa mint's gold dobras from these opening years of his reign funded diplomatic overtures as much as military ones — Fernando's shifting alliances with Aragon, Castile, and England made hard gold coin the only reliable language of foreign negotiation.

The "Pé Terra" designation distinguishes this type from later dobra variants issued as Fernando's monetary policies evolved under war pressure.
