During their time in power, the Sandinistas established the roots of a democracy. They also introduced extensive literacy and vaccination programmes.
Ailsa Henderson, a worker for aid agency Christian Aid in the country, says the revolution markedly improved conditions for Nicaragua's poor - and that life would have been much worse without it.

improve Nicaragua's dire economic situation.
