It was agreed that the Amu Darya river would form the border between Afghanistan and the Russian empire. The agreements also resulted in the Russian Empire losing control of most Afghan territory it conquered, with the exception of Panjdeh. The Pamir Mountains were demarcated as a border line between the Russian Empire and Afghanistan as well. The Taghdumbash would be the subject of a later Afghan-China agreement. To conclude their agreement, one peak was named Mount Concord. In exchange for a British agreement to use the term "Nicholas Range" in honor of the Emperor Nicholas II of Russia on official maps, the Russians agreed to refer to Lake Zorkul as "Lake Victoria" in honour of Queen Victoria of the United Kingdom.
