Introduction

Leon Trotsky used a lot of pseudonyms, pen names and alias all his life, for various reasons (political persecution first by Czarist and later by Stalinist repression organs, living under illegal or half-legal conditions, factual prohibition of publishing and so on). He used those alias as writer, editor and contributor as well as in false passports.
The name 'Leon Trotsky' [Russian: Lev Trotskii, or Lev Davidovich Trotskii, cyrillic: Лев Давидович Троцкий] itself is a pseudonym which was adopted by young Lev Davidovich Bronshtein [cyrillic: Лев Давидович Бронштейн] – his real name by birth – when he had to put a name into a falsified passport which he needed to escape from his first Siberian banishment in 1902. By the way, 'Trotsky' [or, Trotskii] was simply the name of one of his prison guards in Odessa.
Trotsky's [Bronshtein's] pseudonyms are listed here alphabetically with some occasional comments. Most of these pseudonyms were used only sporadically, during certain periods of his life, while others were used in earlier as well as in later years. Many pen names were used by Trotsky only in correspondence but not in published items, others were used exclusively in internal bulletins of the Left Opposition movement.
Please note that variant forms of spelling (e.g. as a result from different transliterations of Russian cyrillic characters) are not listed in the following table but in an appended note below.
