At the beginning of the November Uprising of 1831 he was sent to London to obtain the assistance, or at least the mediation, of England, but the only result of his mission was the publication of the pamphlet Mémoire présenté à Lord Palmerston (Warsaw, 1831).

[1] On the occasion of the Galician outbreak of 1846, when the Galician peasantry[2] massacred some hundreds of Polish landowners, an outbreak generally attributed to the machinations of the Austrian government[citation needed], Wielopolski wrote his Lettre d'un gentilhomme polonais au prince de Metternich (Brussels, 1846), which caused a great sensation at the time, and in which he attempted to prove that the Austrian court was acting in collusion with the Russians in the affair.

On the other hand, the Polish nobility should – in his opinion – accept Tsarist rule and take part in the Empire's political life instead of calling for independence.

Initially the motivation of his project was connected to the period around 1815 when Tsare Alexander I signed the Constitution of the Kingdom of Poland, and even made promises to extend liberties to the parts of the Polish-Lithuanian Commonwealth directly incorporated into Russia (the "Taken Lands" Ziemie zabrane).

Ultimately, Wielopolski gave up such ideas and proposed instead: formal condemnation of the November Uprising and acceptance of the Romanov dynasty's everlasting rule over Poland, expecting in turn from the Tsar the restoration of Polish liberties, a semi-independent government, curtailment of censorship, and the closure of Russian Military Courts.

His proposal, unfortunately, was rejected, and the Tsar decided to make various limited concessions only when it was too late, and the streets of Warsaw were running with blood: "No constitution, no Polish Army, nothing like political autonomy; instead administrative freedoms with nominations for Poles, not excluding Russians".
