What was tsarist ideology?
Tsarist autocracy consisted of principles promoting the idea of the divine leader leading his people like a parent and caring for and protecting them in a paternal manner. People fell in happily enough with the image of the tsar being their ‘little father’ and were taught by the Russian Orthodox Church to obey the tsar because he had been anointed by God.
If Capitalism did not need Ideology, then it wouldn't be ideology at all. Ideology is the organized ideas which give a new direction to the people in society for revolution and because Capitalism is being able to own private land, businesses and organizations; there must be entrepreneur and because entrepreneur come up with ideas, there is the ideology. The free market economy, in essence, is basically the source of ideology in capitalism.
