阅读下列材料,完成下列问题。

材料一 恩格斯在《反杜林论》中指出:“这种历史情况也决定了社会主义创始人的观点。不成熟的理论是和不成熟的资本主义状况、不成熟的阶级状况相适应的。”

材料二 如图是1909年法国雕塑家沃蒂耶在贝尔?拉雪兹公墓创作的一座浮雕作品。一位袒胸身着长裙的妇女,中弹后仰,像神圣的天使般深情地张开双臂,像慈祥的母亲悲痛欲绝地拼死庇护着身后若隐若现的受难者,墙面上弹痕累累。雕塑下面刻有雨果名言:“我们所要企求于未来的是公正,而不是复仇。”雕塑取名为《献给历次革命受难者墙》。有人解释说,这位母亲护卫的人群正是巴黎公社社员,她体现了法国母亲无私的爱。于是,人们怀着崇敬的心情把它称作“公社社员墙”。但令人奇怪的是,当这座浮雕揭幕以后,当时幸存下来的巴黎公社社员都一致否认它是“公社社员墙”,也从不去那里拜谒献花。

                                     

材料三 《 * * 党宣言》指出:无产阶级将利用自己的政治统治,一步一步地夺取资产阶级的全部资本,把一切生产工具集中在国家即组织成为统治阶级的无产阶级手里,并且尽可能地增加生产力的总量。

(1)材料一中“社会主义创始人”指的是谁,根据上述结论简述马克思主义诞生的历史条件。

                                                                                                                                                                

(2)结合所学知识说明为什么幸存下来的巴黎公社社员拒绝承认它是“公社社员墙”,简述巴黎公社的历史意义。

                                                                                                                                                                

(3)简述苏俄(苏联)(1917~1936)和新中国建立初期 * * 党人是如何“一步一步地夺取资产阶级的全部资本”的?
