Diocletian's stay in the East saw diplomatic success in the conflict with Persia: in 287, Bahram II granted him precious gifts, declared open friendship with the Empire, and invited Diocletian to visit him.

Diocletian's attempts to bring the Egyptian tax system in line with Imperial standards stirred discontent, and a revolt swept the region after Galerius ' departure.

Diocletian's reforms in the region, combined with those of Septimus Severus, brought Egyptian administrative practices much closer to Roman standards.

Antioch was Diocletian's primary residence from 299 to 302, while Galerius swapped places with his Augustus on the Middle and Lower Danube.

Diocletian's reply: " If you could show the cabbage that I planted with my own hands to your emperor, he definitely wouldn't dare suggest that I replace the peace and happiness of this place with the storms of a never-satisfied greed.

In keeping with his move from an ideology of republicanism to one of autocracy, Diocletian's council of advisers, his consilium, differed from those of earlier Emperors.

As with most Emperors, much of Diocletian's daily routine rotated around legal affairs — responding to appeals and petitions, and delivering decisions on disputed matters.

The most that can be said about built structures under Diocletian's reign is that he rebuilt and strengthened forts at the Upper Rhine frontier ( where he followed the works made under Probus's reign, both along the Lake Constance-Basel as well as along the Rhine – Iller – Danube line ), in Egypt, and on the frontier with Persia.

Most importantly, Diocletian's tax system and administrative reforms lasted, with some modifications, until the advent of the Muslims in the 630s.

He was baptized and instructed in the city, and lived in Palestine in 296, when Diocletian's army passed through the region ( in the Life of Constantine, Eusebius recalls seeing Constantine traveling with the army ).

Since Diocletian's Tetrarchy ( 296 ), it was the major province of a diocese confusingly called Galliae (' the Gaul s '), to which further only the Helvetic, Belgian ( both also Celtic ) and German provinces belonged ; with the dioceses of Viennensis ( the southern provinces of Gaul ), Britanniae ( also Celtic ) and Hispaniae ( the whole Celtiberian peninsula ) this formed the praetorian prefecture also called Galliae, subordinate to the western emperor.

While no contemporary sources on his life are preserved, later sources and legends claim that he died during the Diocletianic Persecution, which ended with Diocletian's retirement in 305. Januarius is the patron saint of Naples, where the faithful gather three times a year in Naples Cathedral to witness the alleged liquefaction of what is claimed to be a sample of his blood kept in a sealed glass ampoule.

He served with distinction as a soldier under Emperors Aurelian and Probus, and in 293 at the establishment of the Tetrarchy, was designated Caesar along with Constantius Chlorus, receiving in marriage Diocletian's daughter Valeria ( later known as Galeria Valeria ), and at the same time being entrusted with the care of the Illyrian provinces.

Sheppard Frere wonders how Carausius was able to win support from the army when his command had been sea-based, and speculates that he had perhaps been involved in an unrecorded victory in Britain, connected with Diocletian's assumption of the title Britannicus Maximus in 285, and signs of destruction in Romano-British towns at this time.

Diocletian's Palace, which later became Split, was largely built with limestone that was quarried on Brač.

A Western Roman Empire existed intermittently in several periods between the 3rd and 5th centuries, after Diocletian's Tetrarchy and the reunifications associated with Constantine the Great and Julian the Apostate ( 324 – 363 ).

While no contemporary sources on his life are preserved, later sources and legends claim that he died during the Diocletianic Persecution, which ended with Diocletian's retirement in 305.

The authorities also constructed the city weather station and two " vidilice ", or " look-out points ", as resting places connected with a long stairway all the way to the Diocletian's Palace, the " Riva " promenade and the rest of the city center.

A transverse street leads to Diocletian's Camp, built by the Governor of Syria, Sosianus Hierocles, with the remains of the large central principia ( hall housing the legions ' standards ).

The Acta of the martyrdom of the bishop Fructuosus and his deacons Augurius and Eulogius document his legend ; they are the earliest Hispanic Acta, " marked by a realistic simplicity which contrasts very favourably with many of the Acta of Diocletian's persecution ".

As Christianity grew and became more accepted by governments, notably with the Edict of Milan, rooms and, eventually, entire buildings were set aside for the explicit purpose of Christian worship, such as the Church of the Holy Sepulcher.

In January 1562, Catherine issued the tolerant Edict of Saint-Germain in a further attempt to build bridges with the Protestants.

France was embroiled in its own religious battles that would only be settled in 1598 with the Edict of Nantes.

The Edict dealt only with Protestant and Catholic coexistence ; it made no mention of Jews, or of Muslims, who were offered temporary asylum in France when the Moriscos were being expelled from Spain.

The Edict remained unaltered in effect, registered by the parliaments as " fundamental and irrevocable law ," with the exception of the brevets, which had been granted for a period of eight years, and were renewed by Henry in 1606 and in 1611 by Marie de Médecis, who confirmed the Edict within a week of the assassination of Henry, stilling Protestant fears of another St. Bartholomew's Day massacre.

During the remainder of Louis XIII's reign, and especially during the minority of Louis XIV, the implementation of the Edict varied year by year, voiced in declarations and orders, and in case decisions in the Council, fluctuating according to the tides of domestic politics and the relations of France with powers abroad.

In October 1685, Louis XIV, the grandson of Henry IV, renounced the Edict and declared Protestantism illegal with the Edict of Fontainebleau.

The Edict of Versailles did not legally proclaim freedom of religion in France – this took two more years, with the Declaration of the Rights of Man and Citizen of 1789 – however, it was an important step in eliminating religious tensions and it officially ended religious persecution within his realm.
