Once the new government had been established and the constitution put into effect, conflict began to erupt among the members of the new ruling coalition. There were basically four major factions competing for power. There were the older conservative civilians led by Phraya Mano, the senior military faction led by Phraya Phahon; the junior army and navy faction led by Luang Plaek Phibunsongkhram; and the young civilian faction led by Pridi Phanomyong.
