However, Prussia was confronted with a fragile domestic political situation in its western provinces at the beginning of the 1830s. Nobles and liberals from the Rhine region were opposed to the administration in Berlin. They were strengthened in their movement for a national constitution by the July Revolution in France and the revolution in Belgium in 1830. In this time of turmoil, urgent official messages traveled slowly by courier on horseback. This was unsatisfactory to the Prussian military, therefore, the proponents of a telegraph network could finally execute a plan for a line from Berlin to Koblenz via Cologne.
