The Roman Republic's constitution or mos maiorum ("custom of the ancestors") was an unwritten set of guidelines and principles passed down mainly through precedent. Concepts that originated in the Roman constitution live on in constitutions to this day. Examples include checks and balances, the separation of powers, vetoes, filibusters, quorum requirements, term limits, impeachments, the powers of the purse, and regularly scheduled elections. Even some lesser used modern constitutional concepts, such as the block voting found in the electoral college of the United States, originate from ideas found in the Roman constitution.
The constitution of the Roman Republic was not formal or even official. Its constitution was largely unwritten, and was constantly evolving throughout the life of the Republic. Throughout the 1st century BC, the power and legitimacy of the Roman constitution was progressively eroding. Even Roman constitutionalists, such as the senator Cicero, lost a willingness to remain faithful to it towards the end of the republic. When the Roman Republic ultimately fell in the years following the Battle of Actium and Mark Antony's suicide, what was left of the Roman constitution died along with the Republic. The first Roman Emperor, Augustus, attempted to manufacture the appearance of a constitution that still governed the Empire, by utilising that constitution's institutions to lend legitimacy to the Principate, e.g. reusing prior grants of greater imperium to substantiate Augustus' greater imperium over the Imperial provinces and the prorogation of different magistracies to justify Augustus' receipt of tribunician power. The belief in a surviving constitution lasted well into the life of the Roman Empire.
With the death of company founder and first CEO Willard F. Rockwell in 1978, and the stepping down of his son Willard Rockwell, Jr. in 1979 as the second CEO, Bob Anderson became CEO and led the company through the 1980s when it became the largest U.S. defense contractor and largest NASA contractor. Rockwell also acquired the privately held Allen-Bradley Company for $1.6 billion in February 1985 $1 billion of which was cash to the owners of Allen Bradley and became a producer of industrial automation hardware and software.
During the 1980s, Anderson, his CFO Bob dePalma and the Rockwell management team built the company to #27 on the Fortune 500 list. It boasted sales of $12 billion and assets of over $8 billion. Its workforce of over 100,000 was organized into nine major divisions Space, Aircraft, Defense Electronics, Commercial Electronics, Light Duty Automotive Components, Heavy Duty Automotive Components, Printing Presses, Valves and Meters, and Industrial Automation. Rockwell International was a major employer in Southern California, northern Ohio, northern Georgia, eastern Oklahoma, Michigan, west Texas, Iowa, Illinois, Wisconsin and western Pennsylvania.
Anderson stepped down as CEO in February 1988, leaving the company to president Donald R. Beall. The completion of the Space Shuttle program and the completion of the B-1 bomber program had led to a decline in revenues, and Beall sought to diversify the company away from government contracts. The end of the Cold War and the perceived "peace dividend", however, prompted accelerated divestitures and sweeping management reforms. From 1988 to 2001 the company moved its headquarters four times: from Pittsburgh, Pennsylvania to El Segundo, California to Seal Beach, California to Costa Mesa, California to Milwaukee, Wisconsin.
At the end of the 1980s, the company sold its valve and meter division, formerly Rockwell Manufacturing, to British Tyre & Rubber. It also sold its printing press division to an internal management team. Following the "peace dividend" after the fall of the Soviet bloc, the company sold its defense and aerospace business, including what was once North American Aviation and Rocketdyne, to Boeing Integrated Defense Systems in December 1996. In the 1990s, the company spun off its semiconductor products as Conexant Technologies (CNXT), which is publicly traded and based in Newport Beach, California. Rockwell International also spun off its automotive division as a publicly traded company, Meritor Automotive, based in Troy, Michigan, which then merged with Arvin Industries to form Arvin Meritor. That company is now known as Meritor, Inc.
In 2001, what remained of Rockwell International was split into two companies, Rockwell Automation and Rockwell Collins both publicly traded companies ending the run of what had once been a massive and diverse conglomerate. The split was structured so that Rockwell Automation was the legal successor of the old Rockwell International, while Rockwell Collins was the spin-off.
