Archduke Ferdinand

According to the script for, Archduke Ferdinand was a Human who was assassinated in Sarajevo.

In an alternate reality, where the Federation was at war with the Klingon Empire, Captain Jean-Luc Picard and Guinan debated the merits of returning the USS Enterprise (NCC-1701-C) to its time period. If the Enterprise was returned, Guinan believed that history would readjust itself. When arguing against readjusting history in an effort to prevent lives that might be lost in a war, Picard gave this example as one where preventing an action from happening would prevent a war and the subsequent loss of life. The line in which Archduke Ferdinand was mentioned did not make it into the final episode.
