It is a blessing for the Joomla! community that the World Conference is happening in Rome. The Roman Empire is probably the best-known example of strong leadership and the highest sense of organisation and authority. Under the Romans, art became the greatest celebration of the power of Emperors, their culture, and their values: through magnificent monuments and legendary events, the ancient Romans conquered pages of history books that were to lead and inspire many generations ahead. Ambition, power, loyalty, success, and happiness were all part of the situational and organisational challenges that the imperial Rome was facing. Stability was also crucial: riots, rebellions and insurrections were rampant in such a vast territory. So guaranteeing law, order, and security within the empire needed astute leadership. There are a lot of good takeaways that ancient Romans can teach us which could be applied in modern business and, most of all, in big organisations like Joomla. So, let me be your tourist guide in the Eternal City while comfortably sitting on your chair! In this virtual tour around the Capital, I will introduce few important concepts that ancient Romans mastered during their long Empire: The role of leadership: how much are they for the community as a whole and part of the community itself. Art as a celebration of values, beliefs and success: how a strong and unified visual language can help engage and inspire the community; attract new people to support the cause; instil a sense of belonging. The Pax Romana: how harmony, duty, decency and wealth (pax, concordia, pietas, humanitas and copia) can work together in reducing conflict, expanding the borders, and maintaining harmony at home. With passion and confidence, I will guide you through the buildings and the history that made the Roman Empire great, hoping that it will be an inspiring and memorable lesson for people leading and volunteering Open Source communities worldwide.
