mid-14c., "oppression for the holding of a belief or opinion," from Old French persecucion "persecution, damage, affliction, suffering" (12c.) and directly from Latin persecutionem (nominative persecutio), noun of action from past participle stem of persequi "follow, pursue, hunt down; proceed against, prosecute, start a legal action," from per- "through" (see per) + sequi "follow" (see sequel).
