While banished and imprisoned by the Ottoman Empire, Baha'u'llah sent letters to the kings and rulers of the world.
"Lay not aside the fear of God, O kings of the earth, and beware that ye transgress not the bounds which the Almighty hath fixed. Observe the injunctions laid upon you in His Book, and take good heed not to overstep their limits. Be vigilant, that ye may not do injustice to anyone, be it to the extent of a grain of mustard seed. Tread ye the path of justice, for this, verily, is the straight path.
Compose your differences and reduce your armaments, that the burden of your expenditures may be lightened, and that your minds and hearts may be tranquillized. Heal the dissensions that divide you, and ye will no longer be in need of any armaments except what the protection of your cities and territories demandeth. Fear ye God, and take heed not to outstrip the bounds of moderation and be numbered among the extravagant."
– Baha’u’llah, The Summons of the Lord of Hosts, p. 188.
