D <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->
Lack of support given to the army
The Tsar refused to consult the advice and the main parties in the Duma. People's anti-German sentiments extended to the Tsar's wife, Tsarina Alexandra, due to her German origins. The poor advisers like Rasputin made the autocracy unpopular. The armies were ill-equipped and not provided with enough support and this further discredited the government and the Tsar.
