What was different about Jewish passports?

Jewish passports, especially during the Nazi era, often had distinguishing marks or stamps that identified the holder as Jewish, such as a "J" stamped on the document. This was part of broader discriminatory policies aimed at isolating and persecuting Jewish individuals. In addition, many Jewish people faced significant difficulties in obtaining visas and were often denied entry to other countries, further complicating their ability to escape persecution. These measures reflected the systemic anti-Semitism prevalent during that time.
