After working as Secretary of State (1790–93), he returned to Monticello and initiated a remodeling based on the architectural concepts which he had acquired in Europe. The work continued throughout most of his presidency, being finished in 1809. Beginning with Jefferson's electioneering for the 'revolution of 1800,' his political efforts were based on egalitarian appeals. In his later years, he referred to the 1800 election 'as real a revolution in the principles of our government as that of '76 was in its form,' one 'not effected indeed by the sword ... but by the ... suffrage of the people.' Voter participation grew during Jefferson's presidency, increasing to 'unimaginable levels' compared to the Federalist Era, with turnout of about 67,000 in 1800 rising to about 143,000 in 1804.
