but in the adjacent Canton of Aargau the cantonal president was happy for the marriage to be contracted, noting that he was "delighted, through this authorisation, to be able to demonstrate that there ..[were].. still cantons in Switzerland that had not fallen prey to the spies". Guests attending numbered various German born (and other) political exiles as well as several originally German successful medical men: they included Adolf Ludwig Follen, Friedrich and Caroline Schulz, Jakob Henle, Karl von Pfeufer and, as the couple's groomsman Michail Bakunin. In April, they took their honey moon in southern France and Italy. There is also mention of a political meeting in Geneva with two "artisan communists" called Weitling and Becker, and of a bathing holiday in Ostend. The couple evidently intended to remain in Switzerland, paying several hundred Swiss francs to the municipality of Augst and several hundred more francs to the cantonal authorities of Basel-Land for the authorisations needed to do so. By the time they died, the investment would probably have appeared worthwhile, but in September 1843 the couple moved to Paris, the city identified in sources as "the waiting room for the [next] revolution", where their first child, Horace, was born three days short of 1844, and where, between 1843 and 1848, Emma became, among other things, a "salonnière" - the hostess of a politically engaged "salon".

There was not the widescale state mandated arrest killing of political opponents that would become mainstream a century later, but in Austria, Prussia and most of the rest of Germany, potential revolutionaries were subjected to growing levels of state surveillance and their publications attracted increasingly effective censorship. By the time the Herweghs arrived there, Paris had become home to approximately 30,000 German political exiles. These included Arnold Ruge as well as Karl and Jenny Marx. Karl Marx and Georg Herwege, both of them newly married writers, closely aligned politically and both new fathers, formed a particular bond, although Emma, again heavily pregnant and hoping to see a little more of her husband, blocked the suggestion from Ruge that the three families
