Diplomat in 450: Athens formalizes the proxenos — Section 660: Athens formalizes the proxen

From ancient royal envoys and Venice's resident ambassadors to the Congress of Vienna and the UN, still negotiating peace one careful sentence at a time. "Diplomat" derives from the Greek diploma, a folded document once issued to Roman travelers as an official pass — a fitting root for a job built almost entirely on paper, protocol and carefully worded documents. Long before any single word existed for it, rulers in Bronze Age Egypt and Mesopotamia were already exchanging royal messengers, gifts and formally worded letters, addressing distant kings as "brothers" to manage wars, marriages and trade without fighting over every disagreement.

There has never been one required path into the job: some of history's most effective diplomats were career civil servants who rose through exams, others were merchants, priests, generals or aristocrats pressed into service for a single mission. What every era shares is the same basic function — a trusted go-between who can speak for a government abroad and report back honestly, because a government blind to what other capitals actually think eventually makes a catastrophic mistake.

This page follows the job from the Amarna letters and Venice's pioneering resident ambassadors to Talleyrand at the Congress of Vienna and the Vienna Convention of 1961. It covers how people actually enter foreign services today, what a single posting demands day to day, who reached the top of the profession and how, and how much of the work — from drafting cables to reading a counterpart's real intentions — machines can realistically take over.
