Executive summary

Adolf Hitler was born on 20 April 1889 in the small Austrian town of Braunau am Inn on the Austro‑German border [1] [2]. He was the fourth child of Alois Hitler, a senior customs official, and Klara Pölzl, his much younger third wife, and his family background and early moves shaped the context in which he grew up [3] [4].

1. Birthplace, date and immediate facts

The basic facts are consistent across major references: Adolf Hitler entered the world on 20 April 1889 in Braunau am Inn, Upper Austria, a border town near Bavaria [1] [5] [2] [6], and is routinely described in encyclopedias and surveys as Austrian‑born before later becoming a German political leader [7] [2].

2. Parentage and family status at his birth

Hitler was born to Alois Hitler, a customs official, and Klara, his third and much younger wife; Alois himself had been born out of wedlock and bore his mother’s name Schicklgruber until he formally changed his name to Hitler in 1876 [3] [8] [9]. Sources emphasize that both parental families came from modest peasant backgrounds and that Alois was a strict, distant figure while Klara was indulgent toward her children [4] [10].

3. Siblings, household life and geographic moves

Adolf was the fourth of six children in a household that moved during his childhood—most notably from Braunau to Linz, where he spent much of his youth after Alois’s retirement from the customs service [4] [8] [6]. Biographical summaries note financial comfort relative to local standards but also record family tensions, particularly the fraught relationship between young Adolf and his father, and the death of his father in 1903 and mother in 1907, events that freed him to pursue art and later relocation to Vienna [1] [3] [2].

4. Contested genealogy and persistent myths

A long‑running rumor that Hitler had Jewish ancestry through his paternal grandfather has no solid documentary support in standard reference work and specialist summaries; Alois’s illegitimacy means his biological father is uncertain, with Hiedler brothers (Johann Georg or Johann Nepomuk) the most likely candidates cited by historians, and no reliable evidence that this unidentified grandfather was Jewish is found in the cited sources [9] [3] [6]. Major institutions and biographies treat that alleged Jewish ancestry as a myth or unproven claim rather than an established fact [9] [6].

5. How “how he was born” is different from how he became a dictator

If the question seeks a causal link—whether the circumstances of his birth explain his later crimes—scholars caution that birth facts (date, place, parentage) are distinct from the political, social and intellectual currents that shaped his ideology; biographical accounts stress that he "was not born a brutal tyrant" but became one through experiences in Vienna, service in World War I, exposure to virulent antisemitic currents, and opportunistic politics in Weimar Germany [1] [3] [10]. The sources supplied document the facts of his origin and early years but do not support simplistic biological determinism; they place greater weight on later environments and choices in explaining his transformation [1] [3].

6. Limits of the record

Primary records from rural 19th‑century Austria are incomplete on some family details—chiefly the identity of Alois’s biological father—so definitive genealogical proof is absent in the available sources and historians treat related claims cautiously rather than as resolved facts [9] [3]. The supplied reporting documents birthplace, date, parental identities, family moves and the contested paternity question but does not, and cannot from these citations alone, establish causal psychological claims about how those origins produced his later actions [8] [9] [10].
