High Porte

The Sublime Porte, also known as the Ottoman Porte or High Porte (Ottoman Turkish: باب عالی‎ Bāb-ı Ālī or Babıali, from Arabic: باب‎‎, bāb "gate" and Arabic: عالي‎‎, alī "high"), is a synecdochic metonym for the central government of the Ottoman Empire.

The naming has its origins in the old Oriental practice, according to which the ruler announced his official decisions and judgements at the gate of his palace. This was the practice in the Byzantine Empire and it was adopted also by Ottoman Turk sultans since Orhan I, and therefore the palace of the sultan, or the gate leading to it, became known as the "High Gate". This name referred first to a palace in Bursa, Turkey. After Ottomans had conquered Constantinople, now Istanbul, the gate now known as the Imperial Gate (Turkish: Bâb-ı Hümâyûn, leading to the outermost courtyard of the Topkapı Palace, became at first known as the "High Gate", or the "Sublime Porte".

When Sultan Suleiman the Magnificent sealed an alliance with King Francis I of France in 1536, the French diplomats walked through the monumental gate then known as Bab-ı Ali (now Bâb-ı Hümâyûn) in order to reach the Vizierate of Constantinople, seat of the Sultan's government. French being the language of diplomacy, the French translation Sublime Porte (the adjective being unusually placed ahead of the word to emphasise its importance) was soon adopted in most other European languages, including English, to refer not only to the actual gate but as a metaphor for the Ottoman Empire.
