As is well known and appreciated by all scholarly circles, Islam is ideologically against the imperialism and hierarchy. With the demise of Holy Prophet, his close companions decided to select a leader to lead the Muslims. This leader was known as the khalifa or caliph. First, there were four caliphs, called, Pious Caliphs or Righteous Caliphs. Then, the first Islamic dynasty was established by Umayyad family, who established the practice of hereditary succession. Umayyads were overthrown by Abbasids. The most important event in this era was the series of Crusades between Muslims and Christians. Ghazi Salahuddin, the great Muslim hero, finally defeated the Crusaders. When Abbasids captured Damascus, one of the Umayyad princes had escaped to Spain to found Umayyad rule there. The Muslims ruled over Spain for nearly eight centuries. In Persia, a new dynasty called Safavids came to power. Then, emerged Zand dynasty, which was overthrown by Qajars and they were in turn replaced by Pahlavis. In east, Mongols converted to Islam and became known as the Il-Khanids. They were succeeded by Timur and his descendents. Later, Ottomans or Turks became the dominant power in the Islamic world. They conquered much of eastern Europe and nearly the whole of the Arab world. This research-based work is a thorough study of the rise of Islam and its journey to success over a millennia. This is an asset for all scholars and lovers of Islamic Studies.

Although considered structurally simple, bacteria are extremely diverse from a metabolic standpoint and are found almost everywhere on Earth in vast numbers-form living in jet fuel and on the rims of volcanoes to thriving in hydrothermal vents deep on the ocean floor. There are both beneficial and pathogenic bacteria- Beneficial bacteria are involved in such diverse processes as digestion in animals, nitrogen fixation in the roots of certain legumes, the decomposition of animal and plant remains, and sewage disposal systems'' Pathogenic bacteria, on the other hand, cause Severe and often, fatal diseases in humans, animals, and plants. The first bacterial disease ever discovered was anthrax(caused by Bacillus anthraces) of cattle and sheep in 1876- This book will be highly beneficial to students, teachers and research workers in the field of plant pathology'' plant protection, botany and agricultural sciences'' contents: Bacteria; Bacterial Diseases of Soybean; Bacteria!
