When Tsar Alexander I visited England in 1814 as one of the victors over Napoleonic France; the Quakers sought out the ruler as they had Peter I. Alexander's evangelical faith was not dissimilar to that of then-contemporary Friends: he "received them warmly, prayed with them, 'fully assented' to their peace testimony, and attended meetings for worship". He also invited Friends to visit his Empire, and subsequently welcomed Quaker visitors, notably William Allen, who worked in Russia to promote education and prison reform, and travelled among the many dissenting religious groups of Southern Russia. In 1817, the Russian government wished to drain marshlands near St Petersburg, and Alexander sent a request for a suitable specialist to the Society of Friends in Britain. Quakers Daniel Wheeler and his family responded to this call; they spent some thirty years reclaiming land near St Petersburg and introducing modern farming techniques. Daniel's wife Jane Wheeler died in Russia in 1832, and her daughter in 1837. In recognition of the Wheelers' services the Imperial government granted them in perpetuity the land in which the dead had been buried: the Quaker burial ground still exists at Shushary, close to the city.
