At the turn of the 19th and 20th centuries, he was a member of the Czech Land Assembly and the Imperial Council; being one of the leaders of the Austrian pan-German movement.

In Vienna, he founded the Deutschnationale Zeitung in 1890 and, with the support of Georg Ritter von Schönerer, the Ostdeutsche Rundschau.

Wolf, von Schönerer and Anton Pergelt lodged an objection to the Baden Language Ordinance of 5 April.

After the premature dissolution of the Reichsrat in 1901, Wolf was re-elected to the 10th legislative period and joined the Schönerer Group (Alldeutsche Vereinigung).

By 1905, most members of the von Schönerer group joined the Wolf's Party, which changed its name to the Deutschradicale Partei.

Wolf sat on the board of the Deutscher Nationalverband, founded in 1909, in which most of the German national elected officials had joined.

During this time he often appeared publicly at nationalist events, including in the Wimberger Hall, where he was seen by the young Adolf Hitler.
