Question: Who was in charge of the provisional government in 1945 of the country of the composer of Der lustige Krieg?

<P0-S0> (The date is officially named the birthday of the second republic.) <P0-S1> At the end of April, most of western and southern Austria were still under Nazi rule. <P0-S2> Karl Renner and Adolf Schärf (Socialist Party of Austria [Social Democrats and Revolutionary Socialists]), Leopold Kunschak (Austria's People's Party [former Christian Social People's Party]), and Johann Koplenig (Communist Party of Austria) declared Austria's secession from the Third Reich by the Declaration of Independence on 27 April 1945 and set up a provisional government in Vienna under state Chancellor Renner the same day, with the approval of the victorious Red Army and backed by Joseph Stalin. <P0-S3> On 1 May 1945, the federal constitution of 1929, which had been terminated by dictator Dollfuss on 1 May 1934, was declared valid again. <SEP> <P1-S0> garbarek was born in mysen, norway, the only child of a former polish prisoner of war, czesław garbarek, and a norwegian farmer's daughter. <P1-S1> he grew up in oslo, stateless until the age of seven, as there was no automatic grant of citizenship in norway at the time. <P1-S2> when he was 21, he married vigdis. <P1-S3> he is the father of musician and composer anja garbarek. <SEP> <P2-S0> The Vienna Walzer Orchestra (German: Wiener Walzer Orchester) is a chamber orchestra based in Vienna, Austria that specializes in traditional Viennese waltzes, polkas, marches and operetta arias from composers such as: J. Strauss II, F. Lehár, C.M. <P2-S1> Ziehrer, among others. <P2-S2> Their concerts also always include performances by ballet dancers and opera singers. <SEP> <P3-S0> the rohingya people have consistently faced human rights abuses by the burmese regime that has refused to acknowledge them as burmese citizens (despite some of them having lived in burma for over three generations)—the rohingya have been denied burmese citizenship since the enactment of a 1982 citizenship law. <P3-S1> the law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. <P3-S2> citizenship is given to those who belong to one of the national races such as kachin, kayah (karenni), karen, chin, burman, mon, rakhine, shan, kaman, or zerbadee. <P3-S3> associate citizenship is given to those who cannot prove their ancestors settled in myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. <P3-S4> naturalized citizenship is only given to those who have at least one parent with one of these types of burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in burma prior to independence in 1948. the burmese regime has attempted to forcibly expel rohingya and bring in non-rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 rohingya from burma, while the rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." <P3-S5> but the origin of ‘most persecuted minority’ statement is unclear. <SEP> <P4-S0> The work was first performed on 25 November 1881 at the Theater an der Wien. <P4-S1> Der lustige Krieg ("The Merry War") is a three-act operetta composed by Johann Strauss II. <P4-S2> Its libretto was by F Zell (Camillo Walzel) and Richard Genée. <P4-S3> The operetta was well received at its premiere, and was performed 69 times during its first run.
