In April 1935, the Turkish government dispatched a lengthy diplomatic note to the signatories of the Treaty of Lausanne proposing a conference to agree a new regime for the Straits
The date is off by a year: Turkey’s note proposing revision of the Straits regime was sent in April 1936, not April 1935.
Full reasoning
U.S. State Department records for the Montreux conference state that on April 11, 1936 the Turkish ambassador presented a copy of a note dated April 10 that Turkey was sending to the parties to the Lausanne Treaty about revising the Straits regime. The same official index lists the Montreux conference as beginning on June 22, 1936, which fits an April 1936 diplomatic note and contradicts the article’s April 1935 date.
