In 1918, Luckievič was elected President of the Belarusian Council of Vilnius. In September – November 1918, Luckievič headed a Belarusian delegation to Ukraine and met there with Hetman
Pavlo Skoropadskyi. He also secretly met with
Christian Rakovsky, a Bolshevik politician. As a result of these meetings Luckievič ascertained that
Soviet Russia would not recognise the
Belarusian Democratic Republic. The Belarusian delegation arrived to Paris five months after the beginning of the conference, when the positions of the neighbouring countries (Lithuania and Poland) had been already heard. The reason for such a late arrival to the conference was the initial lack of finances and the necessity to wait for a loan from Ukraine. Luckievič stayed in Paris for three months. In July 1919, he established contacts with
Ignacy Paderewski, Prime Minister of Poland and Head of the Polish delegation, and handed over a draft agreement “On the Creation of the Union of Two Sovereign States – the Belarusian Democratic Republic and the Polish Republic” to him. This agreement specified provisions for close cooperation between the two countries and also had a secret attachment on military cooperation and mutual actions on establishing borders with the neighbouring countries. Ignacy Paderewski invited Luckievič to
Warsaw. On 1 September 1919, the latter arrived there but neither could meet with the Prime Minister, who had earlier left for Paris, nor return to Paris because the Ministry of Foreign Affairs, unlike many other countries, did not recognize the passport of the
Belarusian Democratic Republic and refused to issue a diplomatic visa to Luckievič. Instead, he could meet with
Józef Piłsudski, but the negotiations did not result in any support for the
Belarusian Democratic Republic. On 1 December 1919, Luckievič returned to
Minsk. After a rift in the
Rada of the Belarusian Democratic Republic, he became President of the Council of Ministers of the Supreme Rada of the Belarusian Democratic Republic. However, having failed to come to an agreement with Poland, Luckievič resigned on 28 February 1920 and left for Vilnius. == In Western Belarus ==
