Question: What is the religion of Ivan III from the country that Kseniya Boguslavskaya's spouse is from?

<P0-S0> Born in St. Petersburg, she studied art in Paris from 1911 to 1913. <P0-S1> Their apartment in St Petersburg became a meeting place for avant-garde artists and poets. <P0-S2> With Puni she published the cubo-futurist booklet "Roaring Parnassus" («Рыкающий Парнас») in 1914. <P0-S3> She returned to St. Petersburg in 1913 and married Ivan Puni. <SEP> <P1-S0> Ivan Puni was born in Kuokkala (then Grand Duchy of Finland in the Russian Empire, now Repino in Russia) to a family of Italian origins. <P1-S1> He is the grandson of an eminent Italian composer of ballet music, Cesare Pugni. <SEP> <P2-S0> in 2011, 33% of germans were not members of officially recognised religious associations with special status. <P2-S1> irreligion in germany is strongest in the former east germany, which used to be predominantly protestant before state atheism, and major metropolitan areas.a 2017 estimate even shows that 37.0% of the german population were nonconfessional.islam is the second largest religion in the country. <P2-S2> in the 2011 census, 1.9% of the census population (1.52 million people) gave their religion as islam, but this figure is deemed unreliable because a disproportionate number of adherents of this religion (and other religions, such as judaism) are likely to have made use of their right not to answer the question. <P2-S3> figures from religionswissenschaftlicher medien- und informationsdienst suggest a figure of 4.4 to 4.7 million (around 5.5% of the population) in 2015. a study conducted by the federal office for migration and refugees found that between 2011 and 2015 the muslim population rose by 1.2 million people, mostly due to immigration. <P2-S4> most of the muslims are sunnis and alevites from turkey, but there are a small number of shi'ites, ahmadiyyas and other denominations.other religions comprising less than one per cent of germany's population are buddhism with 270,000 adherents, judaism with 200,000 adherents, and hinduism with some 100,000 adherents. <P2-S5> all other religious communities in germany have fewer than 50,000 adherents each. <SEP> <P3-S0> religion is a collection of cultural systems, beliefs and world views that establishes symbols that relate humanity to spirituality and, sometimes to moral values. <P3-S1> while religion is hard to define, one standard model of religion, used in religious studies courses, was proposed by clifford geertz, who simply called it a ``cultural system. <P3-S2> ''a critique of geertz's model by talal asad categorized religion as`` an anthropological category.'' <P3-S3> many religions have narratives, symbols, traditions and sacred histories that are intended to give meaning to life or to explain the origin of life or the universe. <P3-S4> they tend to derive morality, ethics, religious laws, or a preferred lifestyle from their ideas about the cosmos and human nature. <P3-S5> according to some estimates, there are roughly 4,200 religions in the world. <SEP> <P4-S0> Her childless marriage to Grand Duke of Lithuania and later King of Poland Alexander Jagiellon was a constant source of tension between the Grand Duchy of Moscow and the Grand Duchy of Lithuania. <P4-S1> Instead of guaranteeing peace, Helena's marriage gave her father Ivan III an excuse to interfere in Lithuanian affairs accusing Alexander of mistreating Helena and repressing Orthodox believers. <P4-S2> This became the pretext to renew the Muscovite–Lithuanian Wars in 1500. <P4-S3> The war ended with a six-year truce in 1503; the Grand Duchy of Lithuania lost about a third of its territory. <P4-S4> Helena Ivanovna of Moscow (; ; ; 19 May 1476 – 20 January 1513) was daughter of Ivan III the Great, Grand Prince of Moscow, and an uncrowned Grand Duchess of Lithuania and Queen of Poland as she would not convert from Eastern Orthodoxy to Catholicism. <P4-S5> Despite political tensions and religious differences, the marriage was a loving one and the royal couple was close. <P4-S6> After her husband's death in 1506, Helena wanted to return to Moscow but was not allowed. <P4-S7> When she planned to run away, she was arrested and reportedly poisoned.
