'peacefully-organized' is a compound word combining 'peacefully' and 'organized'. 'Peacefully' originates from 'peace', which comes from the Latin word 'pax', meaning 'tranquility'. 'Organized' comes from the Greek word 'organon', meaning 'tool' or 'instrument'.

'Peacefully' evolved from the Old French 'paisible', and 'organized' from the Medieval Latin 'organizare'.

Initially, 'peacefully' meant 'in a state of peace', and 'organized' meant 'arranged systematically'. The compound word retains these meanings.
